 New new new new new new new. All right. Let's kick it off. Okay. Got a couple of revisions This is a revision for the ESP 32 s2 feather All these boards got there's like a bunch of visions because the battery monitor speaking the battery monitors the battery monitor chip that I originally used when I Designed these feathers the LC 709 203 very very cool battery monitor and got discontinued and so we had to replace it So he's all got respawned to use the max 17 048 And also we did the silk screen I was at it. I think it's much more legible using penguin It's otherwise the same so we're gonna update the Tutorial for the max 17 048, but I love this new battery monitor. It's basically just as good Maybe I'll update to the bq battery monitor because we just covered that But it's been revised so you can get the new version and you can see on the back It says max 17 048 battery monitor That's how you know what to version you have other than the fact that the silk screen is fancified Next up We've also updated the 1.2 inch seven segment led backpack They're featuring the ht16 k33 is an I squared C to led matrix driver We have these in a variety of configurations sizes. This is like a massive Chunky 1.2 inch high digits You do have to this is just the backpack is that the led display itself which you know if you see in the next image what the outline of it would be and What's updated that so it was kind of about you know, we talked about how the 300 revisions Sort of things they did is first up and now has to make you keep warts So it's plug-and-play much easier to use you don't have to solder in that head If you don't want you to conduct wiring much easier Second I've added a little boost converter so one of the things about the 1.2 inch led segments is that the leds there's two leds in series in each Segment of the digit and so you really need five volts for it to look good because it's two volts plus two volts If you're at 3.3 volts, it's very damn. You only want five and so Historically, I said well you can run it three volt logic, but you'll also want five volt power Well, I've updated now so you can run it at five volt or three volt any mix of match you want Because built-in is now a five-volt little boost converter That will give you you know a hundred milliamps just all you need to drive the segments at five volts cleanly Even if you're powering it from three volts so great for use with steveqt because Oftentimes you're plugging into a three volt microcontroller like an rp2040 or a sandy 21 or you know a Raspberry Pi or whatever and it has three volt power and three volt logic So a very big update to two big updates, but this one. I think this will make it a lot easier to use Next up Okay, next up we've got a PAM 8302 breakout we've had a Breakout board version of this like breadboard friendly version for a long time But I want a one that's plug-and-play that is pre-soldered ready to go You don't have to do any soldering to get it working You have terminal block on one end the speaker You have the JST for audio input on the other and it's just a kind of nice, you know Three-watt class T amp low-cost simple by default. It gives you about 14 DB of gain, but Into a 4 ohm or 8 ohm load, but if you look at the next photo, there is a little volume control knob It's a potentiometer that you can twist to reduce the input from you know can be up to three volts peak-to-peak input You know reduce it down to reduce the gain so it doesn't you don't blow out your Setup so I have a little demo. We have a demo. I have a demo Showing the kind of configuration because there's you know, we have a lot of amplifiers and I'll explain Why you want one or the other? Oh, man? I just I don't know. Sorry I was about to hit autofocus and I hit power instead. We're back. Okay How did we how did we survive hold on it takes a second it does but then then it's all okay fine You can zoom in if you want to I know well I have a lot of stuff this overhead can boot up faster if you accidentally turn it off if you turn it off Why would anyone do that? Yeah, I don't know. Okay, so what's nice here is that? Again, it's solder-free. This is a prototype. It's green the final version is blue or black But green I don't know sometimes I'm feeling green Inside there's a JST two millimeter pH input with and you can use we have cables or like a dollar piece Black is ground red is power three or five volts will work and then white is signal in and the signal is Capacitively coupled here so it can be DC reference. It doesn't matter Well, AC couple it on the input and then the potentiometer is the gain And and then there's the amplifier. There's a couple capacitors and then output You can is a bridge-tied load to in this case. It's a four ohm speaker and up to three watts So it's it's fairly loud and I don't want to get us into YouTube trouble. So I'm just gonna quickly Turn it up Stop it, okay, but you to police you to police a cop now to everyone's just Like it's cops ready. They're just like I'm gonna turn you in cuz you're doing something. Yeah, I know But this is great Like for example, this is circuit Python and it has three volt peak-to-peak output But you know, I also tried this with line level output from my computer and it works great You know because you have enough game and then you can use the use any Flathead screwdriver to adjust the gain and you know, don't don't play copyright music ever Works with pretty much anything. It's just a straight analog audio in to Class D amplifier out very simple, but really great when you just have my controller on your PWM or Pure DAC output and you want to amplify to a speaker. Okay Except the star of the ship side to lady our community our team It's higher stuff native for the community that keeps things going in all sorts of ways cops. That's a Yeah, there's nice cops too, but I'm just saying like everyone needs to stop turning each other in and let's all get together and Make it sure stuff. Anyways start over the show tonight. The product is that that it's the prop maker feather So let's I'll show this demo on the over. Okay, so let's go straight to it So the pot maker feather is the latest in our RP 2040 all-in-one feather line This is because we had a lot of people who were making projects with our prop maker feather wing and the feather M4 And the feather M4 has been really hard to keep in stock because the samd 51 is still affected by the chip shortage somehow And people set the solder together and there's two pieces and it like they wanted better quality audience I was like, oh, you know, maybe I'll just make it all-in-one feather. Actually, you know, let's give myself to credit Dan Halbert said why don't you make it all-in-one feather? That's a good idea. So I did so so what this has a good next image is The left-hand side you've got your usb-c and your battery input and your RP 2040 chip So it's a dual core 130 megahertz processor. So you can Do sensing playback audio do circuit Python or micro Python or Arduino with it There's a reset button. There's a bootloader button. You can also use as a user button After it's booted you can use it as an input There's a steveqt port eight megabytes of flash so lots of space for storing audio files or Sound fonts whatever you want to call them or animation instructions There is an accelerometer kind of in the top right corner. It's a list 3dh 3x accelerometer with tap detection So really good for motion sensing on the bottom right. There is an i2s max 98 357 3 watt digital amplifier So this takes takes digital signal i2s from the rp 2040. So it gives you really high quality audio output Up to three watts. So it's good for you know powering fairly large speakers For props and robotics and metronics. There's also a little servo port We had a little space left over and I was like, well, what are we going to use it for? And I think phil b was the one who was like, can you stick a servo? Connection there. I don't know. Somebody said so and I was like, yeah, it's a good idea So I did so you can plug and play a servo inside and then there's terminal blocks for the outputs So the neopixels For a button input and for the speaker output you've got these terminal blocks So you can really quickly wire up a project and there's probably a lot of projects you can do with minimal soldering And you don't have to solder to the feather itself You just use a terminal block. So let's go to yeah And the overhead thing I'll say is uh, you know a while ago, I think it was A decade ago. I'm just like, you know, it'd be really cool if one day Disney did like imagine you're in the box To you have the next generation of people who are doing like all the cool animatronics and more and like Disney's so gigantic now It's like it'd probably be impossible to find anyone who could help make that happen So I'm just gonna call it that it's like this is one of the things that you can do Video, sorry audio You could do robotics. You could do lots of things in a really compact package and Make your own this gets this could put you on that path of Making like pretty intense. Yeah, I mean, I think was with a product or feather wing We learned a lot like it was a good thing But I think I learned a lot like people really want i2s digital Output sounds really good And um, they want terminal blocks. They could plug in unplug stuff in a servo port So I didn't have the servo plugging before so it was it was making a little bit of noise So let's try this again And this is signal it can run Scripting languages on the yeah, yeah, it's like pretty intense. Um, yeah, I can also run off of the battery Which is kind of nice. So I'm gonna I'm how much flash is on it. This has eight megabytes of flash There are lots of space for audio and more so runs off a battery here This is a button input. So one of the terminal pins is just like a gpio. So in this case, you don't want to press it The new pixels go it's also playing audio, but um, you don't have to believe me And then this is the servo output. So, you know, it's just slowly moving the servo back and forth But that's handy if you want to do Projects where there's a little bit of motion involved. Maybe you want to you know move a little eyeball or move a head back and forth or Have something spinning, you know, you could have um, there's continuous rotation servos as well And the neopixel output has a five level shifter So you get nice clean neopixel output and then the power to the neopixels and this Servo and the audio amplifier can be turned on off instantaneously. So there's a transistor that can turn off those external, um Power outputs and the reason you might want to do that is uh for quiescent power usage like the rp20 40 Isn't it's very low power chip, but still, you know, neopixels do draw current even if they're not lit It's this would let you just completely kill all that power and mute the amplifier for sure And then um, you know, this boot button here when I press it, you know, it turns this led white And then of course you can add more sensors and capability over the stem and qt port just plug in Vertically into it. Um, this one has a broken connector because it's mine, but imagine it didn't have a crack in it Plug in, um, you know a gyroscope. You can plug in OLEDs. You can plug in More servo drivers. You can plug in You know an nfc rfid reader, whatever you want into the i-squared c and of course you have all the header pins as well So you're like 21 gpio on top of that For any kind of analog reading or digital control Can't get to up to a tft. What have you it's a good regular feather But I think a lot of it's built in I kind of like that you may not need um More circuitry or soldering to get most projects off the ground. Yeah All right, and uh, that is new products of the week this week
