 Live from New York, it's Ask This Engineer. Hi, everybody, and welcome to Ask Engineer. The most fun you're going to have Wednesday at 8 p.m. Eastern. It's me, Lady Aida, the engineer with me is Mr. Lady Aida. We are broadcasting live from downtown Manhattan, the home of Adafruit, where we make and manufacture and tutorialize and photograph and video all of your favorite electronic parts and tutorials and more. And do that jam-packed show one hour of all the electronic maker, hacker, creator news you can possibly handle. I can't wait to get into it. We got so much going on, kicking off this March strong. Let's get this show on the road. Mr. Lady Aida, what is on tonight's show? On tonight's show, we are still opening safe. We're still wearing masks and more. We'll talk about our open safely plans and more and all the things that are going on. But we are shipping your orders. Our team and tire, tire team, thanks you. So thanks for keeping us in biz. Coming up on a year of this. Show and tell people around the world showing and sharing their projects. Lady Aida, I'll talk about who's on the show and tell. And what they share. Time travel, look around, world makers, hackers, artists, engineers. This week, we have jobs on, job on the jobs board, jobs.adafruit.com. Got some Python on hardware news. Got some main New York City factory footage and more. 3D printing speed up. We have did you can't need to represent INMPI. This week is going to be from pro amp new products. Got some top secret. Can answer your questions. We do that over on discordadafruit.it slash discord. Journal, 27,000 of us now. That's a lot. That's a lot. All that and more on you guessed it, ask it in general. Yes. Okay. All right, well. It's you and me we're doing the show. Yeah, first up, like I said, we're still open. We're still chipping. Looks like we're through a big chunk of what this pandemic is going to be. It's like most people are agreeing. Yeah, I hope so. Yeah, there'll be some stops and starts. There'll be some ups and downs and bumps in the road. Different states do different things. But even in New York now, the emphasis is on getting vaccinated. And then I'd say, like figuring out what's open, how many and what things are coming next. So it seems like the page is getting turned on those things. So thanks for keeping us safe everyone in Adafruit who works there. We have some good protocols. We managed to keep our team safe as best we could over the last year. And then also all the orders that we've been shipping out. Yes, we've been able to do it. Yeah, so we'll see how the next few months go. Last year in March, we were shut down. All businesses were shut down in New York. And we were manufacturing essential goods for ventilators, for PPE. I mean, it was not boring. That's for sure. And we also didn't have a lot of information at the time. So we think that we'll probably all start to see, like we could even tell from our sales, like more schools are reopening, more schools are buying electronics. Our numbers are good compared to last year, because last year there was a lot of things that started, like in February basically. Yeah, so just slow down a little bit. Yeah, started to. There was like weird supply issues. There was a lot of stuff that was happening. It was like clearly there was something going on. That's when we made our preparations to figure out how we were going to get through, which could potentially be the next year or so. So that's what's going on right now. And stuff that we do when you place an order to reward y'all out there. The easy one is just anything that's over a dollar in the US, we have our hundred days of masking up. We are, let's see. Halfway through, yeah? Yeah, just about. And it's one of the things we want to do. So we toss in a mask and save it, give it to a friend, write yourself, and those go in each order. That's right. Also. We also have other freebies. So $99 or more, you get a free pro pro half size breadboard, perfect for taking your solderless breadboard projects and making them permanent. At $149 or more, over there, you get a free STEM IQT board. We have an assortment of about 25 of them boards we'll pick from to send you. If you make an account, you'll get a different STEM IQT board every time. We got sensors, accelerometers, and breakouts, and controllers, and GPIO expanders, and all that good stuff. $199 or more, you get a free, sorry, you get free UPS ground shipping in the content of the United States. So it's high quality, trackable shipping, perfect for when you want to make sure you get your thing. We're still seeing some delays with USPS postal. So if you do use that, just be aware, it's got more delays than UPS, which is getting back on track. And then $299 or more, you get a free circuit playground express. Our all-in-one development board that's got LEDs, and buttons, and sensors, and capacitive touch pads. It's a great way to program in Arduino, Circuit Python, code.org, CS Discovery, RASP, what have you. Pretty much everything is supported and there's no solid recording. You just jump right in and start making. So it's perfect for beginners. Okay, next up we have Chantel, Chantel we do every single week. We did it, who's on the Chantel this week and what did they share? I'm glad you asked. We had, we had a lot of people come by. Just cool. A lot of people from the community, a lot of people from Adafruit, kicked off with Kevin from Digikey. He just got his Pico RP2040, put Circuit Python on it and got some Neopixels blowing. So he said it was the easiest Circuit Python slash microcontroller project. He's worked on it and he's excited to see how good a combo of Raspberry Pi hardware and Adafruit firmware is together. That's my favorite, it's like peanut butter and jelly. Raspberry Jam and peanut butter, whatever, you got it. We also had from the Adafruit team, Erin, she published a shadow box guide today. This is cool, it's like a scenery shadow box that knows what time it is and it displays like the sunrise and sunset and during the day it's light and at night it's, it's got like sparkly stars sort of effect using a mag tag and some Neopixels. GP, I did an Epic guide. If you ever wanted to make your own keyboard and you were scared, like how do you do it? Do you have to learn Eagle Cat or Cat-Cat? No, you can do it in fritzing with a Pico and Cherry MX switches. He shows you how to make any kind of custom keyboard you want up to I think like 26 keys. So you got a lot of options there for pretty big keyboards without having to do any, you know, matrixing or multiplexing or diodes or anything. So check it out, great for making little Maco keypads. You can get PCBs now for like five, 10 bucks a piece. It's awesome. So take advantage of that checkout fritzing for a very easy way to make your very first PCB and then come show a tell and bring it by, show it off. Jepler also published a guide, a beginner guide to PIO which is the RP2040 like state machine system. We have an assembler in Circuit Python so you can really easily get started with learning PIO without having to build your tool chain up or compiling things. You can do it all in Circuit Python for that instant feedback loop. It takes you from blinking and LED, sorry, turning on LED and blinking LED to writing neopixel data out. So it's a beginner guide and then you can look at the Raspberry Pi PIO tutorials and books that they've written and PDFs to learn more about PIO. And then before you know it, you're bit-banging HDMI. Melissa came by with a microkin back. This is a computer from the seventies that you program by pushing buttons and looking at the LEDs. This is a remake. She's done a video on her YouTube. Check it out. Non-Pedro previewed this coming next week's 3D Hangouts project. It's MIDI Fighter, Colab, Non-Pedro and Liz. So you know it's got that music. It's got that 3D printing. It's got a Pico. It's got LED buttons. It's a really fun build. It's got like a cool handle. I think it'll be a fun project for DJs or people who want to just press arcade buttons and make music go. It's also got a cool LED display built into it. So there was a preview guide is coming next week. Scott has been working also on some back-end stuff for the RP2040 and Circuit Python, defining every single SPI non-volta memory chip, you know, M-RAM or F-RAM or Q-Spy Flash and defining the little differences between them so that we can make sure that we can support any chip in Circuit Python, especially for the RP2040, which has a very particular way of configuring chips. For those of you who are like working with execute-in-place code and you're like, that's right, every chip is a little bit different and it's really annoying. Check out this project. You might find it handy. We're hoping that it gets included in a lot of different people's projects as a database of all the different chips available and their configuration differences. Lucien made a Dynamixel Featherwing. If you have Dynamixel motors, you've got feathers and you want to combine them, check it out. I just finished and published his Dynamixel Featherwing. So it'll be cool. Chris Young is always working on cool accessibility technology projects. This time taking the configuration files that we used in Arcada, pulled out all that stuff, the mass storage for Arduino, the JSON stuff for Arduino and made it so that Arduino projects could be configured by plugging them into a computer, shows up as a disk drive and then changing the JSON file on the fly. They also worked on with Bill, a QT Pi hat for Raspberry Pi that turns it into a little GPIO expander and remote. Micah made a MIDI controller, learning how to DJ and has an old DJ controller but wants like more buttons and stuff. So using a Raspberry Pi Pico made of like a fully featured MIDI controller with the potentiometers and buttons and all that good stuff. So like, I love all these HID and MIDI projects. In a had a soft robotics project. It was cool. It was like this inflating silicone blob. Looks like a lie that had like LEDs behind it. It was for an installation. Hopefully we'll get some video of this project because it was cool. Also using a Raspberry Pi Pico. I love all these projects. People are taking like low cost mic controllers and building with and they used PIO as well. And then Mark came by and showed off their very first DIY PCB for a temperature sensor. Okay, it's part of our Infrared Live series of shows. If you're watching this right now, it's Wednesday, PM, I'm asking an engineer. Used to show and tell, 730, but these are shows on Wednesdays. Desk of Lady Eda was on Sunday. Lady Eda, you showed off a bunch of stuff. I think the biggest chunk of the segment was about this module. Yeah, we got some samples of, I think the BG95 and EG95 Quectel cellular modules. We also showed off, oh my goodness, what did we show? I think we showed off the ESP32 S2QT QT Pi design that I made and what else did I show? There's a few other things. I think we showed off the Trinkie. Oh, the Neo Trinkie. And I think I even did another preview of the Feather RP2040 because we were about to ship. So lots of good stuff happened in Desk of Lady Eda, you can, basically it's a hole into my mind. It's like, what am I working on? Watch the show. Then, Where are you? We do, The Great Search for Digikey, where Lady Eda uses all her powers for good and finds stuff on Digikey. So what did you? I believe it was, it was the Wi-Fi antennas, right? This week? Yeah, so we showed a Wi-Fi antenna that was designed for the ESP32 S2QT Pi. No, sorry, that was last week. Okay, what day is it? The antenna that we did. Forgot what I said, sorry. We were doing, It was the SAMD21. It was the SAMD21E18. So people who want to use SAMD21, it's been a month. For people who want to use the SAMD. Well, I also named the file ant, so I thought it was the antenna too. No, because we have the antenna. Okay, so, yes, hi. For people who want to include the SAMD21 into their boards, I show you how to spec the different kinds of SAMD21s. I sometimes use the G18, sometimes the E18, but I've also seen people use, like the J19 you can use, or even the E15. What are all these numbers and letters mean? I take you through how to decode the part number, the differences you're gonna find between them and why you might end up picking an industrial temperature instead of commercial temperature if the parts are in stock. Also my favorite package of all time, QFN. All right, and if you wanna learn about antennas that was a week before. Sorry about that, yes, a week before we did antennas. And we also pro-ant. We have antennas today too. This is the theme. Tonight's theme is antennas. I mean, they're ants, they get into everything. All right, GP's product pick week is every Tuesday, and on this Tuesday here is a one-minute snippet. Show up next week, same time, same place on Tuesdays, and you can get a live stream from product page and a discount just for that time. TSL2591, it is a high dynamic range light sensor, and I've got it plugged in over the Stem-AQT cable to this Metro ESP32. What I'm showing is the total lux. If I take a pretty powerful flashlight and point this at the light, I'm gonna jump up to around 300, 400 lux. Okay, what's the difference between this flashlight and let's say the sun? So I've positioned a little hand mirror outside, and you can see my hand here kind of blowing out. I'm gonna take the meter and lift that up and put that in the sun, and you can see now we're at around 30,000 lux. That's my product pick. It's the TSL2591 HDR High Dynamic Range Light Sensor. Okay, and on Thursday is GP's workshop, so you'll be able to see that then. Let's do some breaking news. Breaking news. Yeah, so. Beep, beep, beep, beep, beep, beep, beep, beep. Yeah, so we haven't been doing discounts, but we do have like the live shows where we do discounts. And this is live. There's not a discount right now, but there is availability of the feather. RP2040. RP2040 right now, the second. Yes. So. I totally didn't forget to do it for the show. I meant to wait until now to do it. Yeah, so. But check it out. I put in a max of, yeah, it's under the what's new. Oh, you can do RP2040. Yeah. There you go. In stock. Max, of course, for two. Yeah. So let me. Yeah, so it's here. There you go. It's in stock. In stock. You can get it now. You can get it now. And make max of two per customer because I want to make sure that I don't know anyone who would want, you know, more than a hundred. But. Yeah, we didn't want to make sure enough for everybody. Okay. So that's in the store just right now. That's our breaking news. Beep, beep, beep, beep, beep, beep, beep, beep, beep, beep. Okay. For those. For those within the now. Okay. Let's continue to go on. Okay. Time travel. Time travel. Things that are going on right now in the world of Adafruit and more. We get two things. Just one is Reminder. Adabox. Gonna be shipping in April. Adabox, April. Yep. So we have a few slots open, but go to adabox.com right now. Sign up. We will run out. I guarantee we will run out. Yeah. That's lots. So sign up if you want it. And then Jobs Word, Jobs This Week. Another one just got posted. This is a physical role in New York or California. So New York City or Bay Area. Is it two jobs? Yeah, Lead Instructor for On-Site Program and Instructor for On-Site Program. So each place, Blue Stamp Engineering, Blue Stamp Engineering, check them out. And then also check out the jobs on jobs.adafruit.com if you want a job or if you have your skills that you wanna post up. It's a good way to do it too. All right. So that was our breaking news that we have. Yeah. What I thought I would do is just let folks know in the chat who are just getting this now. I will put the URL. So yeah, these are gonna go really fast. Well, we did a very small run to start because we always do a small run to kind of get the manufacturing going. You know, get our yield, test procedures. You know, if folks who do electronics know, it's like your first run is when you want to debug things, find out what goes wrong. So we're gonna do more. Don't worry. We have parts to make many thousands. It's just we don't have those in stock right now if we run out, because like you're not watching this live right now or whatever. Sign up and I promise you, we have a lot of parts where you're going to make a lot. We will have enough for everybody. But get them now. But if you can get them now, I would get them now. Yeah. And so this may be one of the things that we're gonna do is like we recover and then like we bring back maybe discount codes for some of the live shows and more. But what we can do right now is there's scarcity and exclusivity, because you're watching this live show and thank you community. So we want to do that. Yeah, I want to give people leave. What's the show? You do either sometimes you get things, right? There's little benefits. And especially when there is a high desirability item and it turns out the timing is good, I put it in way before the show or in the middle of the show. Thanks, Alex. We'll keep trying to do like fun stuff like this. There you go. Get your yanky hands. Yeah, next up, let's do some Python on hardware news. Okay, speaking of. Okay, big news. 70 single board computers now support CircuitPython. That's right. If you want to check out Tom's hardware, Scott, we did a developer on CircuitPython. He was on Tom's hardware. And then they did a separate story about Scott being on there and they're like, hey, CircuitPython might just run on a Raspberry Pi. Yeah, he did leak his idea, which is he wants CircuitPython to run raw on the Broadcom chip. Yeah, we have Blinker, which is basically like libraries. Linux, yeah. And it's like, you know, CircuitPython for Linux. And then being able to like treat a Raspberry Pi as a microcontroller is an interesting idea. Well, I mean, the Pi 400 would be an amazing like, you know, little tote CircuitPython board. You know, I get it. I see why this is a, it's a fun idea. But check it out. I mean, I think it's, it was a really good roundtable. I listened in. They talked about CircuitPython, about Blinker, RP2040, about like what's coming next, right? A lot of people are like, you know, I think there is a lot of excitement for this year. I think, like you said, people are like, they want to have stuff happen. They're like, they're ready to do stuff again. I think like the whole world has that feeling right now. And so this was, it was a really cool, positive video chat. Yeah. So 70, single board computer is now support CircuitPython. That was our big news. Blinker brings CircuitPython APIs, CircuitPython libraries to single board computers. Another milestone, 2000 people in our CircuitPython subreddit. Thanks to everybody who's there. We try to cover like greater Python news. Yeah. I mean, like, like, you know, Blinker, it runs on CPython. So we're, I'm always interested in what's going on with Python in general. And it's interesting. It's like, what, what does the, you know, I have my own opinions about Python, but I want to hear about what other people think so. So some survey results came in from 2020, 85% main language for secondary language. Why do they like it? Simple syntax is going to learn syntactic sugar. Python experience, 20% of folks have been using it for three to five years. So anyways, check it out. That's from the Python foundation and JetBrains. Raspberry Pi turned nine. Yeah. And actually Engadget just turned 17. Wow. I was second authored Engadget. Oh my God. 17 years ago. It can drive. Yeah. Engadget is around. Engadget, yeah. Engadget is around. I was doing writing a popular science, I think. Oh, they're still writing. I think I was, yeah, I think I was a senior under popular science and Pete Rojas was visiting Microsoft. I was there in an event and it wasn't even, site wasn't even really released and he was going through some names and he was asking me what I thought about Engadget. I'm like, oh, that's a good name. He had left Gizmodo or was leaving Gizmodo back during the blog wars. Yeah. I lost my grandmother to the blog wars. It was Nick Denton versus Jason Calcanus. Wow, no matter who dies, you win, right? So anyways, that was 17 years ago for Engadget and then Hackaday I started when I was doing stuff with Engadget. That's like, is it 14 years now? How old is that? That is a 16 year old because it was pretty fast. Oh man, yeah. It's still around, it's just going strong. Yeah, and then other, you know, other anniversaries Raspberry Pi nine years ago totally transformed the way we were doing a company in electronics and more. No, we got into it. I jumped on it real fast. I was like, this is cool. There was a lot of scarcity for the Raspberry Pi when it came out. So we decided to do something completely different instead of trying to hoard them and try to sell them and disappoint people. We just had it. So if you order $300 and more on our site, you get a Raspberry Pi. So that was unique and weird and interesting and a lot of people did it. So it was good, worked out. So happy birthday, Raspberry Pi. We were thinking about talking about like the Chumbie at the time. And that was the first, yeah, that was like the first that was the first like Linux-y thing that we were like, okay, this is where it's going. And then Raspberry Pi kind of you can still see my learn guide on the Chumbie. I was like, okay, here's how to connect an accelerometer to the I squared C port. I mean, it was pre-blinka, but it was like, the idea was still there was like, how can we, you know, how can we use Linux sort of like an Arduino, like a microcontroller, right? And I think it was, it's a powerful idea. You know, it's actually interesting. So here's like, I'm gonna give people a story. So there was, you know, an open hardware slash Arduino summit and it was like around nine years ago. Cause remember like the Raspberry Pi had just come out and I remember that folks were sitting around and were like, what's the future of Arduino? And I remember it wasn't me, but somebody said Raspberry Pi, like the idea of a Linux computer being able to do all the things that an Arduino can do is the future. And I think we actually turned out to be, it is the future, but it also, it's shared, right? I mean, Arduino is now, it's from like 15 years ago, but I think it's great for people. Some folks use Arduino, some people use Raspberry Pi. It's good to have multiple options. And especially now with a circuit Python, I'm trying to combine the two. You can see my Linux Australia conference talk, 2021. And I go through all this in about 45 minutes. Okay. Other stuff, don't forget tomorrow, Scott is doing his deep dive, circuit Python. All about Tamil. News around the web. JP stream this tomorrow, but you can see some of the things that he's been working on, especially specifically circuit Python stuff. Cascade, this video's got posted. Check them out. Yeah. Debra had some of her works and more using circuit Python and Pi Cascade's presentation. Sony is doing a webinar on April 8th. They bumped it a month. Had a program on microcontroller using circuit Python. You can check out all the things that Sony's up to. It's kind of cool. Sony's adopted circuit Python for their Sony's presence board. You can, lots of stuff going on in the world of micro Python and circuit Python. Pico projects. So this is a galloping horse animation on the Pico using circuit Python. This is a QTPi USB media knob and rotary encoder. It's using circuit Python. Filming guy's stream in. He's been streamed. Check it out. Yeah, that was a cool library pull request and development of the Laura radio project stuff that's going on. And you can check it out. This project was cool. So this is a BTC thing, so I found this. So there's a person on Etsy selling matrix portal, like AidaBox is basically kitted up with like, you know, Bitcoin or whatever, like, you know, Wall Street bets meme stock on it. I just thought that was cool. That's like, neat there. And they even say, like, you can configure this really easily. You just, it plugs in and you change a disk, like a file on the disk to change what, whether you want Ethereum or you want Dogecoin or you want, you know, what stock ticker number you want. And I thought it was neat to see like Etsy, right? This crafty making site selling completed circuit Python projects. I don't know. I thought it was cool. It's that easy to use. So there's lots of bad things about this pandemic. There is. Really? And there's lots of bad things about it. And one of the bad things about it is some of the things that you used to do, you don't get to do anymore. So if I were to write an article about circuit Python or Python on hardware, just like I used to back in the day of other things. And, you know, right now there's AidaFruit razor focused. No, we can't do anything else. So you can't, you can't, you can't write some of the articles about this thing that's been happening in the world of electronics. You can, I think right now your choice is either do it or write about it. You can't like do both, at least not for me. So one of the things I would talk about is this was one of my tests a long time ago on how I would talk about electronics. So back in the day when I was at MAKE, one of the things I used to say, and this was when MAKE and Etsy were the same size and we were in like- No, they were in the same building. We're in the same building together. And I said, once the makers- The quarter style. Well, I was like once the makers are using electronics from the maker world in their Etsy store sales to power things that they're just selling, they're not gonna, they're not selling electronics and how to write code. They're selling animatronic things or signs or something that is, you know, it's more considered a handcraft that's not in electronics. Etsy wasn't an electronics marketplace. Although I did try to do MAKE.etsy.com, other site story, but one of the bits of success is if you're making a technology that allows artists to put electronics into something, that's when you know you did a good job. So Arduino had some of that success. And now like as we bring Python to hardware, you're seeing that now. If someone's using your, in this case, CircuitPython idea of like, oh, just plug it in. It shows up as a drive and that's where you configure stuff. And you don't even need to know how to code, but it's powerful enough where it could just be used like that. You did a good job. So I thought that was neat. And that would be an article I would write. You know, Python is coming to the craft world and coming to the world where you need to power it with electronics, but what is the programming language that you would ever use? How would you do this? Yeah. So anyways, this is cool. Turned out matrix portals. That's how you know. That's how you know it worked out. All right. Also it's applying Libs things, the contribution, CircuitPython, MicroPython plotting. This is interesting. Embed did a questionnaire and it's very embed focused, but it did have some interesting stuff because it divided up, you know, academic, hobbyist and professional and asked like, it shows some of the differences. I thought there was some interesting stuff even for folks who are not using Embed within the Embed ecosystem where they're using microcontrollers. Very interesting stuff. So check out the developer survey and they had a lot of responses too. So it's a big community. You can check out some of the new hardware. This is a Pymeroni Tiny 2040 board. Well, CircuitPython? Yeah. So... Yeah, I got a lot of RP24s. We're gonna see a couple of months of this as folks get so many Pico. Yeah, but this is another thing too. It's like, if you're going to have a product like Kibo with a Pico, what's the easiest thing to use and happens to be CircuitPython? Yeah. So that's kind of cool. All right. We've got some new tech. So if this is needed, L-Cars for E-Ink. Check out our AR app. Full color POV display with a PyPico and that's our LED tape. And then TwitchStream playing around with new hardware and CircuitPython. A MIDI interface and a Citron maker PyPico. It's got everything built into it. It says everything. Okay. And we have some coming soon. We're gonna be talking about soon on our show. And the guides and updates. Some more projects, three in and two libraries. And with that is your Python and hardware news this week. Okay, Lady, we have 2028 guides. That's how we prove that we're an open source company. I know, so much open source hardware. Let's talk about the guides. So we're mixing it up a little bit. I have to actually change the text at the top because it's not just new guides. It's new and updated guides. But I like to talk about the updated guides. We updated the Whereas We Pie Pico Getting Started guide. Just before the show, I think we probably added links to the new PIO Learn Guide that I'll talk about in a second. The shadow box with internet clock with neopixel visualizations. We talked about that. We also have a little video we'll show shortly. That's from Erin. She's a mag tag as a Wi-Fi clock, which is great on its own. And then it controls neopixels to make the display match the outside colors and sunrise and sunset and nighttime effects. So it's kind of like a little window into the outside. Card in this project. So we have these gas sensors. And I was reading an article in the New York Times about folks who have reduced sense of smell because they've got COVID and sometimes it takes a while for it to recover. And somebody who was being interviewed said, they're scared of drinking milk because they can't tell if the milk has gone bad. And I said, we can solve this with science. So Carter actually even shows a scientific experiment he went through using a clue and one of our gas sensors. And you can really easily detect when milk has gone sour. And so you can make a, you know, it's a good science project for kids. But also if you want to, you know, you have maybe congenital anosmia or you just want maybe something in your fridge to tell you when your milk has gone bad. So you don't have to smell it. You can build your own milk freshness checker and it's got this cute cow that tells you whether your milk is good to drink or a little suspicious or definitely no good. Jeff Epler also wrote a guide about using PIO that's the state machine system in Circuit Python. So you can do like the really quick iteration. We wrote an assembler in Python. So you don't have to recompile your PIO code. You can like write the code in Circuit Python, save it and it runs immediately. So if you're interested in learning PIO, this actually might be a really fast way to get started. Actually you don't have to worry about your tool chain. And then JP did this like epic, epic project really with so far one of my favorite guides of the year making your very own circuit board, your first circuit board using Fritzing. It's okay if you've never done a circuit before, board before even tells you how to send out the boards to Oshpark or JLCPCB to get them back and build your own custom Macro keypad. You can customize it again however you want at potentiometers, add LEDs, buttons, sensors, whatever. But a great project. I know people love making their own Macro keypads. It's a great starter project and the PICO makes it really easy to solder it right on. And then we have a couple other updated guides. Display.io guide got updated with some, we have some new text updates and some more debugging info for Raspberry Pi Zero headless quick start guide to get people who have confused Pi Zeros back up and running. Okay, and then I'm gonna play the little shadow box video. Yes. Make a custom shadow box with animated Neopixel lights and an Adafruit Mag Tag. The Wi-Fi enabled Mag Tag animates the pixels in a slowly shifting color palette that sets off your artwork. We've taken this project a step further with a Wi-Fi data feed that changes the color palette based on the time of day. Each day at sunset and sunrise, the colors will slowly shift through glorious purples and oranges before blending to a starry sky at night or a sunny day in the morning. We'll show you how to take your favorite photographs and transform them into a vector image that can be cut on a vinyl cutter. Customize the size to fit your shadow box frame and plug your Neopixel strip into your Mag Tag. Cut out your design on a vinyl cutter, then stack the layers to create the shadow box effect. See the full build tutorial with sample code and sample files on the Adafruit learning system. Link's in the comments. Thanks for watching and remember to subscribe for more fun Adafruit projects. And next up, some New York City Factory footage. Well, guess what we made this week? Here is a tester. It's an RTC tester. It's a P.I. Flash. It's like more PCBs. This is our original. Before we did STEM at QT, this was actually what STEM wasn't gonna look like. This was our first idea for like a plug-and-play board and we thought like, oh, maybe we'd have alligator clips on it. Lots of iteration here at Adafruit. And it would be a New York City Factory footage without a sunset. Here's New York. It's like a shadow box, but real. Yeah. Oh, that's nice. Nice night lighting. And they're still building, the Disney building across the street from Adafruit. They're gonna find Vision's body somewhere down there. So we got some 3D printing this week. We have one video, one speed up. So take it away. Yeah, Pedro. Okay, and 3D Hangouts is every single week at 11 a.m. Eastern time. You can learn how to make all this stuff and more with Noah and Pedro. That's right. All right, Leida. Okay. Let's do this. Digikey and Adafruit, present. All right, this week's INMPI is from Pro Ant. Pro Ant. Oh, Pro Antennas from Pro Ant. This is the first time we featured them and they have this antenna that I saw in digikey.com slash new, which I always recommend everybody check out. There's a new couple of new sensors that just popped in today. So this is the, let me get the part number totally correct. It is the Pro OB607 onboard SMD2400 stamped antenna. It looks like this big chunk of stamped metal. There's also an eval board that comes with it. It's kind of just like the antenna where there's an SMA connector on the back so you can use it to evaluate this antenna as a couple of capacitors as well. You're wondering, hey, you know, Pro Ant, that sounds like familiar, right? Like where have I heard that? Where have I heard that? No, it's not the name of the professional ant farmer association. It's a technology that's also licensed and on the back of the Raspberry Pi, right? So you see here on the back of this Pi Zero, it says uses an antenna technology license from Pro Ant. And if we go across on the other side, we're like, well, I don't see that metal antenna. That's because the antenna they license is actually like a PCB design. And it's like this thing, this like, you know, line with the ground plane and then this like kind of cool triangular shape with a couple of passive components, like a very inexpensive antenna. And it works really well. I mean, we've actually seen this on a couple of Raspberry Pi products. So this is cool to see like they, they're like doing really cutting edge antenna technology. So, you know, not only do they have the stamped antenna, but if you are doing a PCB and you're doing a lot of them and you want a very low cost antenna that I think is probably smaller and gives you better results than an inverted F, although I don't know for sure. I didn't look at the licensing documentation, but I assume it must be better because otherwise they wouldn't be using it. Check out Pro Ant for licensing antenna technology. So you're also wondering, you know, kind of this like bent wire antenna thing. Where have I seen that before? You probably saw it on the back of the Pi portal pint because we use U-Blocks modules. And hey, look at that. It's a Pro Ant antenna. Might be the same model, might be a slightly different one, but it's just kind of 3D antenna. It pops up and above the PCB. You can also see this antenna style used here. Oh, look, it's another Pro Ant antenna. This is on the Pico ESP32. It's a dev board that we stock as well. And then what's this? Oh, look, Espresso fuses it on their PCBs as well for their Pico board. So I was, you know, I've seen this bent metal antenna and I've kind of been like, what's the deal here? And so when I saw it come up on INMPI, I was like, this is cool, I'm gonna pick some up because I'm always working on Wi-Fi or Bluetooth, 2.4 gigahertz stuff. And what's the cool thing about this antenna? Well, the cool thing about this antenna is it's got really great gain. It's really inexpensive. It's, you know, sense. It's definitely gonna be less than like 30 cents or so. It comes on a tape and wheel. It's really easy to pick in place. It's fully metal, so you know it's gonna reflow quite nicely. It's got really nice circular emission. You know, it's off of the PCB, so you're gonna get more 3D gain across, you know, the entire sphere of emission. The gain is a max 4.9 DBI. You know, the datasheet has more graphs. And it has less than, sorry, it has, do you mind making a little larger, just because I... Oh yeah. Sorry, the text is so small. It has better than 65% efficiency, which is really great, and less than a negative about 7 dB return loss. So if you compare that with your inverted F antenna, you know, you're gonna get definitely more gain. You know, here even the max gain is gonna be 3.3 DBI. And the reflection is negative 15 dB instead of negative 7. So, you know, yes, nothing is gonna be for price, a printed PCB antenna. But hey, you know, you can do better than that. Get this, you know, 3D stamped antenna. Pick and place it on your design. They're not very big. And, you know, I will say that I, when I see a lot of people using these antennas, I know there must be something good going on. So, you know, I know a lot of folks use ceramic antennas or 3D antennas, and sometimes your space requirements dictate that. But if you have a little bit of space and, you know, the height doesn't bother you, especially if you have a tin can so that maybe the height would be equal to the antenna height, check out these antennas. They seem to have really good performance, and I'm looking forward to designing one of these antennas into my next Wi-Fi or Bluetooth design. There is a, you know, there's a couple of different versions. This one is this big. This is a millimeters. It's got a couple of solder points. It, you know, I like that it has a couple multiple solder points, so it's nice and stable against the PCB. But it looks like they designed a couple different types of these stamped, you know, 3D antennas. Like I said, they're pretty cheap. You buy them by the real. This particular part is Pro-OB607, but the entire Pro-Ants, you know, they have many boards in the series or many antennas in the series, bigger sizes, you're gonna get more gain, maybe less return loss. So, you know, you figure out how big your antenna can be and check out these antennas. They seem to be quite the pros at antennas. That's why they're called Pro-Ants. Yeah, and you can get this. I've run digikey, digikey.com for it's that short URL. 4FDZ8M42, and then for the product number 1532 Pro-OB607, and then there's a couple variations, like I more said. Yeah. We also have a video. That's right. They have, look, go subscribe to the Pro-Ant YouTube channel. They only have like a couple dozen subscribers. You can be first to comment on their videos when they do more videos. So check out this video. Today I want to introduce you to a demonstrator for the new Recon. Oops, sorry. I think I gave you the wrong link. Oh yeah. Oh, I apologize. And then in here. I apologize. That was last week's video. Exciting. I'll send you the video in a bit, and we'll... Yeah, well, when we add it to the, what we'll do is we'll stop this here and we'll, for this segment. Yes. And then on the page that people are gonna see this all the time, that's when we'll have that video in. Or they can just go to the YouTube, youtube.com, search for Pro-Ant, and check out the video. It's the video they have on their page. All right. All right, thanks everybody. And that's IonMPI. Good job. IonMPI. Oh, Gidoki. Thank you NWK for posting the video. All right, thank you for posting the video. Yeah. It's a lovely one-minute video. All right, let's kick it off. Let's get any products. All right. Okay. In stock now, we had it in the shop, but now it's actually available to purchase. We have the Raspberry Pi Compute I-O board for the Raspberry Pi 4 compute modules. We have some compute modules, not the Wi-Fi ones in stock. I think we have like the two gigabyte MMC, no Wi-Fi, basic ones. This I-O board has everything. Real-time clocks, breakouts, multiple USB ports, ethernet, two HDMI. It's got like three camera connectors or something. It's got multiple display connectors. It's got a PCIe slot. I mean like it's got everything, DC power jack. So if you're designing something with the Compute Module 4 from Raspberry Pi, and you don't know what you need, use this design, figure out the minimal hardware that you need for your final product, and then pair everything else away. And you can basically use this as your development board for the Compute Module, which plugs right in. Let me grab my Compute Module and I can even show it off on the overhead. Okay, so this is the Compute Module plugged in. So it's got these nice little sockets, so you can plug it in right here. PCIe, power supply, fan controller, DC, I think this is probably up to 12 volts input, micro SD card, two USB, ethernet, two HDMI, real-time clock, standard Raspberry Pi, hat two by 20, two camera ports, two display ports, and then I think this is, yeah, the configuration jumper. So yeah, especially the PCIe, that's kind of cool. I didn't even know that that was available. So yeah, I don't know, plug in whatever card you want under PCIe there. Okay. All right, so check it out. And it doesn't come with the Compute Module, but we stopped the Compute Modules, plug them together. Next up, we have from, we actually, these are called like black pills because they're kind of like an upgrade of the blue pills. This is an STM32F411 chip. I think it has 512K of flash and then 128K of RAM. There's also a spot on the bottom for a Q-Spy flash, should you want to solder one in. This has support and Arduino, who STM32 Arduino. There's some micro Python port I found for it, it's linked in the product. And we also have circuit Python support for it. It's got a couple of buttons on it. Bootloader button, reset button, user button LED. It's kind of minimal, but it does have a lot of GPIO and it's a nice powerful chip. So if you want to get going with STM32, especially in circuit Python or micro Python, where you really want like a Cortex-M4, you want like a good amount of memory, this board will give you a lot of GPIO, the power stuff, USB-C and you can kind of get going. So we don't make this, it's by React, but if you look online for Blackpill, STM32, F411, you can see lots of tutorials and projects people build with this board. Okay, next up. Next up, it's this mini PIR sensor, which I can also show on the overhead. So we have large PIR sensors that have wires on them. This is a little cute PIR sensor, what's so good about it? Well, it plugs into a breadboard, it's kind of tiny and it's really simple. You just give it three to 12 volts on the power pan, ground pan and then the output just toggles high for two seconds whenever somebody walks by, has about three to five meter distance, but it can work much closer as well. You wave your hand in front of it or a person walks by and it detects motion. So these are often used for automatic light turning on systems and bathrooms or motion detectors or intruder detectors. But a lot of people want projects where when a human walks by or maybe a large animal, it's detected. So this PIR sensor will do the job. So let me zoom in. So you see there's a regulator here. This, these are these three pens you can see. There's very small text. It's a negative sign for ground, O for output, VCC positive. And then there's this little lens over the actual PIR element and a regulator on the back. So yeah, you just give it three or 12 volts and it's just, you plug into a breadboard. It's very easy to use. You will have to have the pin read by a microcontroller. I tried to kind of pick it up to like, like some PIRs they can drive like a relay or like an LED, but this output pin isn't very strong. So you'd want to read it from microcontroller and then have that microcontroller or transistor and then have that actually power more high-powered output. Okay, next up, we got a bunch of wires. Yes, we've got pigtails. These are JSTXH pigtails. Let's talk about them all at once. We've got two pair pigtails. We've got three pair. You got three wires. And guess what comes after three? We've got four pair. And we've got five pair. And last but not least, six pair. So, you know, you want some nice chunky wires. These are really easy to plug and unplug. You get two halves, right? You get the socket and the plug with various pins. We also have these in like JSTXH, sorry, JSTPH. And we also have these in PicoBlade, which are very small. The other little chunkier, they use 26 gauge wire. The connector itself can carry about three amps. It's a nice chunky connector, so good when you need a little bit more power or you want something that's a little less fiddly than the PicoBlades. I'll show it on the overhead real fast. You can see one example, but they're all pretty much the same thing. This one is the three pin and there's a nice key here. So, you know, you can't plug it in backwards. Ooh, that's nice. It can only go in one way and it has a nice little locking action. So it's, you know, it's solid against pulling, but then when you really want to, it's friction lock. So each connector half is 2.5 millimeter pitch. It's not quite one inch, 0.1 inch. It's like a little bit less, right? It's 2.5 millimeter, not 2.54. That said, you can pretty much fit this into something that has 0.1 inch pitch. You know, especially the two, three, and four pin. Once you get to five and six, it's a little bit fiddlier, but, because, you know, the tolerance does add up, but it's close to ish 0.1 inch. And so you can, if you really want to, you know, plug this side into header, you can kind of get away with this like this PIR sensor. It's like, well, you know, it works just fine, even though technically it's a little bit different. So, JCXH pigtails in multiple sizes. I love having these pigtails because I see people try to crimp their own connectors. And if you're really good at crimping, you can, of course, make any connector you could ever want. But if you're like me, you sometimes don't want to crimp, you just want the cable, and you solder the ends to whatever you want, and you're good to go. Okay, and to start tonight, besides you, the community, our customers, our team, is what we were talking about before is the Feather RP2040. Woo-hoo, if you're watching this live, you might even have some in stock. That's right, the Feather RP2040. We got those chips in last week late, and then on Monday, we got the PCBs, and we ran, then we did a small run, and we'll be doing more. Okay, so it's up here, so I can point out all the things we got going on. So it is a Feather. It's Feather-shaped, two inches by 0.9 inches. USB-C connector, a lot of our newer Feathers have USB-C. It's got the standard JST battery connector. It's got battery charging built in. There's two buttons. On the left, there's a reset button. On the very right, there's a boot select button. For those who've played with the RP2040, you know that you have to press the boot select button while resetting or powering up to go into the UF2 bootloader. So that's a great way to easily load code onto it. You don't need any special DFU utils or a special SWD programmer. But speaking of SWD programmer, there is an SWD header in the middle. It's not populated. Why? Because we wanted to keep this Feather nice and slim. A lot of people like to kind of like make slim Feather packages, and the SWD header would make it kind of extra tall. So we left it out. That said, we sell the connectors to like a dollar. You can buy them Digikey, a couple cents. Solder on an SWD connector, should you wish to connect this up to a debugger like your JLink or whatnot and use the debugger tools? Not a lot of people use the debugger. So again, it's an optional thing. There's an onboard Neopixel that you can control. It's connected to one of the pins that isn't brought out. In Circuit Python, we use it to notify you about your program status, but use it for whatever you like. There's a crystal and of course the RP2040 chip, right, this cool dual Cortex M0, runs about 125 megahertz. It's got 264K of RAM in it, which is wonderful. And because it has RAM, but not Flash, if you look on the very right-hand side, kind of between the chip and the boot select button, there is a Q-Spy Flash chip. That's the execute and place Flash. It's eight megabytes. It's really chunky because it's going to be shared with your Circuit Python or MicroPython code, as well as the firmware running on the RP2040 itself. So for Circuit Python, at least, we take about a megabyte and then you have seven megabytes left for all the files and fonts and libraries and images and animations, audio, whatever you have, you stick it on that disk drive. So you have seven megabytes left over, which is a good amount. If you're wondering why eight, you can watch last week's Desk of Lady Aida and I'll tell you the secret, which is it was a thing that worked. And then last but not least, there's a STEMI QT connector. So you can quickly connect all sorts of sensors and devices, OLEDs and such. Into the end, we even have a Grove adapter cable. So if you have Grove, I-Squared-C sensors, plug those in as well. The idea is to make it super easy for people to get started with Circuit Python on the RP2040. And speaking of, I have some feather projects I thought I would show off, maybe on the overhead. So starting with, let's see which demos work. It's always the joy. Okay, so this one. And you decided, hey, I've got this feather on a new chip, why don't I- Let's connect to a feather wing. Why don't I see how it works? Yeah. Make sure everything still works. Pretty much, that's how the sausage is made. So here I've got the RP2040 and here is the feather M4 RGB feather wing, right? So this is for RGB matrix displays. As seen on the matrix portal, people love these. You know, they're used in pixel purses. They come in all sorts of sizes and it's a really easy way to add tons of LEDs to a project. And I just have it on a doubler. So they're just connected side by side so you can see both of them. And then when I power this with five volts, this will power up. And then the matrix, I'm going to, this is connected to this matrix, which I'm going to move out of the way. Oh, goodness. I'm having a, oh goodness, how do I get back? Am I running Android on this thing? Nope, that didn't work. Shoot, the magic. Well, I don't know what I pressed. Thank you. Okay, so this, hi, live demo. So the RGB feather wing is connected up to this matrix into running this little animation, which is taking icons from a bitmap and then like swirling them around in circuit Python. It's just an easy demo to show, quick animations of iconography and bitmaps on RGB feather wing. So that just shows like, you know, you can plug and play existing feather wings onto your RP2040 feather. The next demo I have, oh my God, I got two demos going, is I took this RP2040 feather. This time I'll be very careful not to press any buttons. This is the RP2040 feather here and I plugged it into an airlift feather wing. So this adds an ESP32 as a Wi-Fi coprocessor. And then I plugged this into a TFT feather wing. So again, it's all feather wings all the way down, powered this off of a battery and then plugged in a temperature and humidity sensor. And then over here, I've got, it's connecting over Wi-Fi and sending the data to Adafruit IO. So like this was a, I don't know, let me get real close. So connecting to Adafruit IO and then sending the data over Wi-Fi through the Request Library through HTTPS, securely to Adafruit IO for data logging. So again, it's all kind of plug and play. You plug in the Wi-Fi feather wing on the top. It uses the standard ESP32 SPI library we've got for Circuit Python. Plug into a TFT feather wing. So now you've got your console, the cute little blinker in the corner, displaying so you can easily see what your Circuit Python board is doing. And then finally, plug and play sensors and then run one of our 300 plus libraries to get that temperature and humidity data and send it online. And then you can see over here, I've got this. So you can do IoT projects with the RP2040 right now. That's right. It's gonna use Circuit Python. So Circuit Python works. So you can see the temperature and humidity. And if I breathe on this, you should see the humidity pop up and the temperature pop up. So maybe I didn't break it. There you go. So humidity from my breath, two or three seconds later get to upload to Adafruit IO and so you can get like instant IoT projects with the RP2040 feather using the existing feather ecosystem, which is awesome. You know, I put these demos together in only a few seconds, a few minutes before the show. You know, just by plugging in the existing parts we have and running the example code that we already have. All right. We only have 40 left in stock, so they'll probably be gone shortly. I know. Okay. So it's about my demos. All right. We're gonna do a top secret and then I got some questions lined up. Okay. From the Adafruit Vault. So I've got this cute little board that I designed. This is called the Neo Trinkie. And this is a Samdi 21 and it's on like a little USB stick with four NeoPixel LEDs and then two capacitive touch pads on the end here. I was really inspired by like the FOMU and the TOMU and the other USB, the other USB plug-in FPGA boards. So you can see like this button makes it brighter and then this button changes the color with the capacitive touch on the end. So like trying to make the lowest cost, the circuit Python compatible board using the Samdi 21, which doesn't require a lot of parts. So it's like very simple and small and even has a little key chain hole so you can like put on your key chain, make circuit Python anywhere you go. Okay. And that's the top secret. So we're gonna go right to questions. Yes. Some folks posted them up. I'm going to get to those Discord and the ones that were in other places I can see. We do that over on discord.igfruit.it Discord here is your URL if you need it. Okay. Okay, so questions are lined up. First up, the Feather Footprint and the Eight Fridigo libraries are useful. Could we get those for the QT Pi, Trinket, Itsy Bitsy, et cetera? That's a good idea. I don't have one, but I know you can definitely use Fritzing because I made sure that the Fritzing objects were PCB friendly. So if you want to make a quick PCB with those parts, check out Fritzing. Okay. Next. How do you, oh, speaking of vision, have you seen any eight fruit hardware in WandaVision yet? So probably they had some- They probably do, but we don't know. Yeah, so they have some electronics in the back that other film productions, it's all like, you know, when you see like Neo-Pixel-y like things or if you make them for a living, you kind of can spot some of the stuff and then later on people will, you know, take photos of closest, especially when the on-demands that they can pause and go to specific areas. Like our stuff is in the Mandalorian, which you need to find out till afterwards when they did like a like, oh, here's like the behind the scenes. Which is part of this entire experience streaming app. So I'm sure there's some in there. We're in the app. Sure, there's some in there. How do you use the extra two megabytes of RAM on the QT Pi on the back? If you're using Arduino as a manual, is there a setting in the IDE? You have to do it manually. Like it doesn't show up automatically, but we have the SPI Flash library, which allows you to read and write to it. And then if you're on the QT Pi, you can use TV USB and have it show up as a disk drive. So like you can, you know, I've definitely used the SPI Flash on SAMD21 boards in Arduino to store files and, you know, to store images especially. So I can do like an image slide show and the images are living on the SPI Flash. But you have to, you have to code it. It's Arduino, so that's how we code it. Next up, with the mini PIR, do you know what the maximum milliamps it can provide? Not a lot. Again, it's the signal output. It's like, it seems, I couldn't get to an LED and it was not super happy. It could light it up, but I'd say maybe one or two milliamp output. Okay, what is one bit ADC? A one bit ADC is, well, it could be like a PWM comparator. I mean like, I don't know what, in particular you're talking about. But there are, if you look at how, you know, PDM microphones work, for example, they are a one bit output that encodes a digital input, but you have to heavily filter it. And PDM is the encoding method. And you can look at like white papers about how PDM microphones are made and it's actually kind of interesting. Like you charge up a capacitor until the comparator with the analog input like toggles and then it switches the output to higher low. And like, if you do that at like a megahertz or so, you can kind of get this like pulse width modulation-ish output that encodes the analog input. Is it better than like successive approximation? I mean, there's pros and cons. One bit ADCs are cheap. That's why they're in PDM mics and they're very simple to implement. They're one of the simplest ones. You don't need any extra circuitry related. It's like a very basic way of encoding analog input. Okay. Next question. How many of the circuit Python libraries will need tweaking to native code for the RP-2040? I mean, well, like two, two, sorry, I lied. So NeoPixel's already been ported. NeoPixel's already been, the underlying NeoPixel write is already been ported over to the RP-2040. And I think pulse-in had to be implemented natively. But I think only like the DHT library and maybe infrared LED stuff are the only two things that aren't currently working. iSqrtZ is, you know, we're still poking at some bugs in it, but that works. SPI works, as you saw, like I had, you know, TFT display and ESP module running on SPI. And OneWire works, because I tried OneWire. So yeah, but pretty much everything should just work. If it doesn't open up an issue, but I think we got like almost everything. Capacitive touch works, we got that going. How many RP-2040s do we have right when we put in drop and stock? I think we put in a little bit more than 100. Yeah, we have about 26 now or less. It will sell out before the end of the night. So kudos for circuit Python, circuit Python, let me test my, for my design in literally five minutes to see what was wrong with that. I noticed that the CP2104 is flagged as not recommended for new designs. If I recall correctly, is part of some feather boards. Maybe I'm just like the party curious if you're already adopted a replacement. No, I mean, there is just the CP2102, I think is the replacement, but you'd be surprised because something is not recommended for new designs. You can still get it for many years. So I'm not too worried about it. We do use it in a couple of designs. Look, when it's completely gone, I will, well, we spin the boards and goodie for us, but I found that it's good to know about things that are being updated, but not to stress out about them too quickly. You'd be surprised how long that they're available in the market for. Okay. What project scenarios would you recommend, like the feather 2040 versus an M4, M0? Well, it's inexpensive, so that's really nice if you want to use this PIO stuff. That's really cool. I mean, it's got basically the price of an M0, but close to the power of an M4, right? So it's nice in the middle. That said, there's a couple of things it doesn't have. It doesn't have a DAC, right? So if you really want something with a DAC, you're missing it. If you need something that has heavy floating points for it, it's still an M0. It's not an M4, it doesn't have a floating point unit. So, you know, there are some things that it's definitely not going to be, it's going to be, I think in many ways, better than just a plain M0, but there's still a lot of reasons why you might want an M4 or like an ESP32S2 or an NRF52840 for wireless. Okay, any plans about the Flash 8 megabytes on the QTiPi, like you do for the feather? We're going to look if I can fit a larger Flash chip because it's a physically larger chip, but I want to try to do a revision. Okay, so we want to know what Neopixels are used for in the Mandalorian. We posted it up. It's aid for Neopixels. It's used to power their razor crest. Yeah, the fifth thing that goes, whoosh! Yeah, it makes a girl. It makes a girl. We've got 22 of these left, and yeah, we do. The Feather RP2040 in Girov has a RevB. Were the changes anything critical? We posted a RevC, you can compare the schematics. Take a look at them, we moved a couple pins around. Nothing a big deal, but if you had, if you're one of the people who decided to make a RevB, you're really on your own. It was not published for people to make and expect support. We do not support the RevB. We're only supporting the RevC. Okay, are there PCB files for the ESP32-S2 mini based on the TFT Feather available? It's not finished because it's not finished. I haven't been able to get the modules, so I will release the PCB files when the hardware's released. We usually do it like within the next few couple days. Reason being, I still have to, I have to get the final modules, right? I only have engineering samples that I don't want. I don't want to release something that I don't know will work with the final modules. Okay, next up, are the feathers generally pin compatible? Yes, they tend to be. There's a few exceptions, like the ESP8266 Feather is very limited, but almost all feathers are very similar in compatibility. I stick the peripheral pins in the same place and the analog pins in the same place. Okay, can you update ESP32 to work as a UF2? No, ESP32 does not have native USB. And we're down to 18. Dude, when it's down, we have to end the show. Yeah, well, we're gonna... We're gonna show you then. Okay, I think I got to all the questions in different chats. Okay. I think that's it, make sure. Doop, doop, doop, doop, doop, doop, doop. Yes, we did. Okay. All right. All right, sweet. There was a question about the... The pricing hasn't been posted for the PICOs by, or the RP2040s by the PyFax. Correct. We don't know that, well, the price of the RP2040 chip is not public. We will not, we cannot divulge any information we may or may not have. No comment. I don't think they publicly posted the price list yet. That's correct, it's not been published. We don't have any information. You might be able to sort of evoke what the price might be based on how we price our products and other people price their products. However, it is not, it's not public. And only the PyFax is gonna answer it. If you ask us, we will tell you to ask them. Yeah, generally until I see it on their website or publicly, you know, we've been able to work on this before it came out and that worked out really well. No one leaked or no one did anything. So for a price list, also like, then you get into like volumes and resellers and stuff like that. So since, from what I can tell, because Pimeroni has a board, Aydford has a board, Spartan has a board, and Reno has a board. Their plan is to have a lot of people make boards with this. Yeah. So it'll probably be published any moment. Couple months. Yeah. Couple weeks, couple months. Next up. Yeah, also, I think when you, if you need chips, I think they have been sending out samples to folks. Yes, but here's a hint, be nice. Yeah. You'll get more samples with honey than with vinegar. So I think the Raspberry Pi folks have been sending them samples out to folks. And yeah. Nice folks. Yeah. And then follow up. Keep an eye on Digi Keysight for our P2040 pricing. Yeah, that's probably. They'll probably stock them like they do other chips. And we'll do one more. This Aydford board to get started with, I would say Circuit Playground Express. Nothing beats a Circuit Playground Express, man. It's got so many projects. It's so easy. Whether you've ever coded before or you're an expert, you can run free R toss on it or make code. I'll do two more. Is there an Arduino core yet? No, they did a blog post. It's on their website. They said they're working on it. Again, we have no information. But here's my guess. Ask Arduino. My guess is they have Arduino Day coming up at the end of March. So they're probably going to announce it then. Maybe it'll be. There is an updated IDE, but it doesn't have anything to do with this. No, but maybe it's a preview hint. OK, how long does it take to average to spin up a board on the pick of place? Two to three hours, I guess. It depends on the complexity of the board. OK, so I got to the last round of questions. Sweet. All right, well, that's it for a question. All right, thank you, everybody. Woo, it's a jam-packed show. Yeah, special thanks to let me make sure I find the folks that are here. I see Kelly is in our behind-the-scenes chat, but I also saw Jessie May earlier. Hey, Jessie May and Kelly. Anyways, either one of you, if you're here. Hi. Hi. And special thanks to everyone in our chats. Yes. Community. Posting links and more. People posting projects, people helping others. Also, you probably have a little bit of time if you want to get one of these feathers. Yeah, Jack, now. Although, again, we will be making many, many, many. This is just our first run. Yeah. We don't do a lot for our first run. It's the right way to go, just in case something's amiss, because we want to get it through the entire testing cycle. We've learned a couple of things also. And so we will be manufacturing more probably this week or next week. And so don't worry if you don't get one. Sign up, and believe me, we will get through all of them. All right, almost that. That is our show for night, everybody. We'll see everybody next week. Thanks for placing orders and more. And thanks for sharing and making code and doing show and tells. And keeping this going for the last year together, we'll continue to go forward, share, and more. Thanks, everybody. That's our show. Here is your moon, Zener.
