 Welcome to the show. It's me JP. It's time for JP's product pick of the week and I am so excited to have everyone here Thanks for joining us over in the YouTube chat as well as the discord and if you're watching elsewhere You want to join in on the chat then? Head to our discord. It's at adafruit i t slash discord jump into the live broadcast chat channel That's where things are going on right here right now So let's see what have we got going on here today The you know what the first thing I want to do is send you on over to the product page for this week's product pick You can watch this show from inside there. It's broadcast from inside the page. This is the URL for it So head to product 4600 or you can use the QR code there if you like to use those sorts of things and go check it out We have a 50% off discount this week on the product pick and you can get up to 10 of them So if you really want to Go go wild with these. This is a great one to do it on super useful helpful Fun little product. So before I say any more about it What I'm gonna do is jump back just a couple years to the product introduction with Lady Aida So take it away Lady Aida Star the show tonight besides the community customers aren't there. Our adafruit team is Qt pie Qt pie. So this is I you know, it's a little bit like a trinket. It's smaller than itsy bitsy It's kind of it's a cute board and it can run pythons. That's why it's called the Qt pie. It also has a stem and Qt connector It's one of our first little boards that has that and that makes it great for plug-and-play projects That use any of our stem and Qt boards and it can also connect to Grove sensors with an adapter cable it can connect to any spark from quick boards as well It's perfect. It's the perfect size because like no other connector would fit on a board this small. So it's a samd 21 e18, you know, the thing is like usbc stemma Neopixel Kessellated pads reset button Kessellated pads. So it's got usbc So you can plug it any which way you want and it's got a samd 21 So it's like for our dweenos projects. It's amazing. It's got great support We've gotten we've written so many tutorials and projects and libraries for the samd 21 It's got 256k at flash and 32k of ram. So you know compared to like an Arduino Uno It's got eight times as much of everything There's a regulator that can supply 500 milliamps of current. There's a neopixel led here So it's got full color and you can turn off the neopixel with a power pin It's got a reset button so you can get to the boot loader or you can reset your project very easily And you don't have to worry about it. You don't even solder it like there's no soldering required to build Most projects you can just plug and play with any of our iSquad C boards and You'd be surprised like a lot of sensors and devices are iSquad C now So you get a lot of pins you get analog output on a0 and log in on a1 and log in on a2 and a3 iSquad C you got uart which also do analog spi These can all do pwm You can do i2s You've got you know one of each iSquad to ur spi hardware support So it's very easy to interface with like any hardware you like Yeah, you can play little audio clips in Arduino. You can control displays You can just have sensor data output serial and then you can just plug into your computer and then either use it within processing or Unity or or what have you so I think it's you know, I wanted to have a Trinket like board with a qt connector and this just was the perfect size It's based off of the seed. We know shall which is the same pin out so you can use the same accessories It's got the same chip But it's a little bit different because this one of course has a reset button neopixel And qt plugs. That's why it layouts a little bit different. That is cutie pie. Yay. It is cute It runs python if you want one pick it up now Yes, that's right. If you want one pick it up now, uh here it is look at It is back. It is our best little friend the cutie pie samd 21 As as you probably know, these have been these at samd 21 chips the m0s They've been really hard to get for the last couple years due to the global parts Shortage and we've gotten a ton of them in so we have these available. You can pick them up today half price Just head Right on over there. Uh, and and you can you can go and get them half price Let's uh, let's talk about this. So That's my product pick of the week this week. It is the return of the cutie pie samd 21 It's a cortex m0 board. It is in the form factor of the seed. We know xiao And as you know in the last couple years since these first came out We've made a handful of different boards in this Size in this form factor with different chips on them. This is the original the the original one right here And the cortex m0 is fantastic We have so many projects that you can build if you look in the learn guides, you'll see there's a ton of stuff You can deal with the samd 21 m0 based projects Some of the things I love about it one usb-c Two the fact that it is usb Hid compliant all the way through so you can do midi projects with it keyboard projects with it mouse projects with it serial stuff All available over usb So it makes it great for those types of projects also because of the stem acute port on there You can plug in the many many many many i squared c peripherals that are available out there And especially the ones that have that stem acute port. It makes it plug and play for example, here's one I was messing around with this stuff again recently. Uh, we've got a little little plug right there. I'm going to plug that in this is a We chuck adapter lets you use various nintendo accessories And a little OLED display so you can see no soldering just plugging and playing and you can get a project up and running You can do your projects in arduino. You can do your projects in circuit python And i'll show you actually one. Here's a nice little Little demo i've got set up of Some of the power of the board here i'm going to reset this switch over Pull a camera out here Some focus got some nice soft focus going there. Uh, so here you can see here's an example of a project where I have A really large number of neopixel leds being driven by Our little friend the m zero. Let me get that. Sorry. Let me get that board stable there And in this case i've soldered some wires to it. So you could do the sort of thing over stem acute In this case. I just went for direct soldering to the data in and ground To the board. I have a data out pin. I don't really need to use that one. Uh, the Board in this case is is a bazillion led. So that's being powered over its own separate connection But you can use five volt and three volt power We have both of those out. So if you need stuff directly off of the usb power you can do that with this board Some other stuff. I'll leave I'll leave this pretty Pretty graphic up here if it'll stay stay put some other interesting facts about the The cutie pie here we've got 11 gpio pins on here. So if you look here's one that's not plugged in so I feel a little safer poking around on it You've got 14 of these pins with castellated pads on them, which means you can surface mount it And this board is Surface mountable because it's got nothing on the bottom. Now you can go ahead if you want to Goose it a bit you can solder on a little extra two megabyte flash chip if you want to But in this in this form it can be soldered straight onto a board surface mount style So we've got three pins up here that deal with power But then the rest of these pins the the 11 pins are usable for all sorts of gpio Digital ins we've got nine analog inputs. We've got One true analog output. You can pwm. I think nine of the pins We've got hardware i2c over the stem of qt port. We also have spi urt i2s for digital audio And six of the pins are cap touch capable so you can do capacitive touch projects with this as well Let's see. What else is there to say? Let me check in with the uh, let me check in with the chats over here Actually, I'll bring up the the discord Where'd you go discord? There you are Excuse me Can you use any inputs for capacitive touch? Yes six of them and I had a project, uh, excuse me Got so excited. I forgot how to breathe I had done a project at one point where I just attached some little sort of spring steel To six pads and I was able to touch those to do capacitive touch input Which makes for really nice wearable projects interactive art types of projects Yeah, dj devin 3 says I like it for small led projects These are great for doing your development on a little plug-and-play board if you want to use that for led stuff for neopixel stuff And they are so darn small They're great for wearables. So dj devin 3 mentioned doing halloween projects stuffing them inside of a mask They're just so tiny. Look at look at this. It's a It's basically Thumb-sized I can't hold my thumb that way under this camera without breaking my wrist, but there you can see Look at that. It's a tiny little board Uh, let's see. What else have I Mentioned um, oh, yeah for usb. You also can use it for storage That's another besides the keyboard mouse midi serial There's also storage so you can save files on to it if you need to It's a 48 megahertz chip and it's got 256 k of flash built on like I said, you can add More if you want we have an a different cut of the circuit python that you can put on called hackspress If you put the two megs on and we've got 32 k of ram on there as well and It is Such a modular system. Thanks to the stemma qt. You can plug and play all sorts of Sensors just endless numbers of sensors and inputs, but we've also got if I let me zoom out here a second and get myself a little more Space to show stuff Zoom way out here. Let me fix that focus again. You can see we have These add-ons That go right on top of or on the actually on the belly of the cutie pie so just like that I've got them in the bags here, but you can see we've got a Neopixel Bff we call them bfs best friends for others so you can hook that on to be a nice neopixel driver board We've got the lipoly. It gives you power and battery and battery charging. We have the Neo key that gives you a key switch mechanical key switch that just bolts right on there And we also have a micro sd card if you have a project that you need to Pull files off a sd card. You can do that as well. And then maybe you're plugged into a display or something else like that So super super versatile board and and a really convenient Board for your projects and really inexpensive normally there's $7.50 today if you head Right here To that url that you see you're going to get them for $3.75 For this board you can't do better than that. That's that's outrageous to have a at samd 21 based Development microcontroller with all of those peripherals all of those add-ons for $3.75 Fantastic Let's see. What else have I oh, yeah, I'll let me jump over here. This is Over in the learn system if you just type in cutie pie You'll see we've got the main Guide for cutie pie can head there. You can also see there are a lot of projects that use the cutie pie here was my my green screen retro reflective led Project we've got a neopixel guide for using with cutie pie activity timer some Other led projects some lighting with lego projects and on and on And if you click on that main Guide right there that'll get you started that'll give you the info you need to update the uf2 bootloader if you need to to put Your version of circuit python that you want on there How to run it in arduino. We've also got the pin out here. Let me show you what all those Uh pins are usable for it's a little small right there But you can see all the a lot of those pins have multiple uses you can set them up And use them the way you want give you a little info about powering it And uh, then example code to run in arduino and in circuit python to get you started So That I think is going to do it. Um, you know, I'll check sometimes I check these a little late So i'm just going to check over in our youtube And Discord to see if there's any other questions or thoughts people have Uh, jim edgar says bought a bunch of these love them. Awesome. That's great to hear Uh let's see dj7 3 one of the most underrated features is the 5 volt out for neopixels at full power You don't get that with most feathers 5 volt makes the neopixels a little bit brighter Uh They ought to say dang it. What else do I need to get? Uh, you can't go wrong with the bffs There there are a lot of fun to have those little uh, plugables as well It's maybe some uh, some of the header pins to to plug those into Uh, you can uh, if you want to Do development on one kind of use it as your development board You can of course solder the pins on it and plug it into a little breadboard Maybe get a half-sized breadboard You can also put a little capton tape underneath the bottom just so that none of those pads Short anything. Uh, and then you can solder it flat right onto a perma proto Maybe like a quarter size or the mint tin one so it makes a really if you need a really really flat Uh pcb for a project that's kind of a nice A little combo there are some of the insulating capton tape and one of the perma proto boards Uh, really nice to make tiny little projects that you can tuck away um Yeah, and like mr. Certainly says it's it is so small compared to a feather And then if you do say hey, you know what there's a feature of the feather I really want let's say it's the battery charging and the jst plug for for the lipo Then you can get get one of these get this, uh Lipoly bff there plug that onto there and you'll you'll get an on off switch And you'll get the charging circuit and the the plug for the battery so Really really versatile all right uh I think Oh, so uh In is this discord is the username asks can you talk a bit about power consumption? Uh, I don't actually I don't know a ton about the power consumption on this the best bet if you look back here at the learn guide Uh is head to the last page says downloads Um, this will give you the datasheet for the chip So you can find out at least that much about it It also give you the the board files and schematics if you look at, um Might be on the pinout sheet Let's see This talks about what you can draw. Uh, so over the three volt line. You can draw 500 milliamps The five volt line is is often tied to your usb. So I think you can get 500 milliamps peak one But i'm actually not sure about power consumption on the board. That's a that's a good question If anyone has any info about that, please Add that to the chat. Um, we also have various um Methods of putting the board to sleep when it's not in use. So then you have a much lower quiescent power on it Uh, rufus said what was the insulating tape called? I couldn't quite get the name. Uh, the the brand name for it is Capton with a k k a p t o n. Uh, it's also called poly polyamide tape. Let me see if I let me jump back to my, uh Chrome browser here Do we have it as capton? Oh, that's the sorry i'm in the learn guide. Here we go. Uh, yeah high temperature polyamide tape, uh, right here Commercial name is capton but known as polyamide tape um Any other questions that looks like it's it All right Well, hey, thank you again so much for stopping by. Uh, there's the site Jump back a couple pages Uh, looks like do we still have them in stock? Yes, looks like we're still in stock with these So you can get that until the show is over. There's the url if you want to Want it nice and big there, uh Get out from under that barcode. You can, uh, get that pricing without a coupon code Just throw it in your cart right now during the show There's also some suggestions for some add-ons there like the if you're wondering about that two meg flash Chip that you can solder to the bottom to use it in hack express mode that's there No coupon code necessary the price is good during the show. It'll drop back To the full price 750 after the show So you'll want to you want to put that through through your cart and into the system before the time is up and With that I will say thank you so much for stopping by today That is my product pick of the week this week. It is the cutie pie sam d 21 cortex m zero Thanks everyone for eight of fruit industries. I'm john park. This has been jp's Product pick of the week. Bye. Bye
