 From the vault, let's start off. We're going to play three videos in a row, and then we're going to look at two PCBs. So take it away past us. Okay, Lady, what is this? This is a Metro ESP32S2, and it's time to design a tester. I'm using a Raspberry Pi. The reason I like the Raspberry Pi is I can run ESP tool on it for really fast programming. And then I have the Metro test itself. And then once it passes test, as you see, it loads Python on. It's going to ship with CircuitPython 6.0 release candidate zero. And then people can always, of course, upgrade to the latest version as we do more versions of six. So it's Arduino Uno shape to give you shields. It's got an ESP32S2 rover. So it's got PS RAM, DC power, USB-C, optional debug port, STEMI QT connector, and a LiPo battery port. All right, it looks like it passed. We've got that rainbow swirl. That's how you know it's good to ship. More rainbows. Hey, I'm working on a new prototype. I just got these PCBs in. This is a 2.9 inch grayscale yank display. I've got four neopixels. Well, I got a solder in the other three, but it's got neopixels up top that are like edgelets. You can like, you know, light up this display. It's got four buttons down here. And on the back, I've got a battery and battery charger, a STEMI QT port, a buzzer, USB-C, and it stars an ESP32S2 Wi-Fi module which will run CircuitPython. And it's got PS RAM and all the goodies for Wi-Fi quickness. So I'm going to do a couple changes. I want to add a light sensor. You recommended the light sensor. And I'm going to get this accelerometer working. And then we're going to have some fun Wi-Fi yank projects featuring CircuitPython. That's the magic. Early due to business. Hey, this is another demo for the yank portal that I've been working on. This one, it's running CircuitPython actually and getting the price of Bitcoin from Coinbase and also just playing the time. I got all four of the neopixels working. And then these buttons also do stuff. And there's a piezo. You can hear the buzzer working. And this is the back. And I got the battery, ESP32S2. And then I put these magnet connectors on. These are like from RGB matrices. So then I can attach it to pretty much anything you want. That's magnetic or, sorry, metallic that magnets will stick to. So very handy way to easily mount it and battery power your yank display. All right. And then we have two things that we posted up. Yep. I got some QT PI boards, NPR-121 capacitive touch. So upgrading a current design to be plug and play. And this is an ESP32S2 board that's in a PI0 form factor. Turns out you have the exact right number of pins. So that'd be kind of fun, especially since like you have two USB connections, one for native USB and one for bug. It can be interesting. All right. We're going to go and answer some questions.
