 This is the new itsy-bitsy ESP32. I designed this board in 2020. So this is one of those boards that's like, oh part shorted is over. Let's like try to get back to it. So we just got these assembled and they're double-sided. They've got the USB serial converter on this side. ESP module with eight megabytes of flash, two megabytes of PS1 on the top. Plug it into the tester and then we're using a Pico using USB to serial to do the programming. Let's give it a second. And it flashes the file. You can see on the computer it's flashing it over USB to serial. So it's doing USB host to the WCH9102 chip to program the ESP32. And then in a few seconds it's going to finish the test. And then you'll see the test complete. 34, 35, 36. Okay. So now it's going to test all the pins. Oh, and this one is not passing. Okay. Then it's fine. You just have to hold it down 31 seconds later. And then the support is done being tested. And then when you reset it, it does a little nice rainbow glow. So this has passed test and we'll be able to get it to the store real soon. All right. And then you're making Swiss up. Okay. So we've checked about the desk of Lady Eda, this TCRT-1000 optical reflective sensor. That's the right angle. That's right. Maybe if you duck your head down, you can see the two things sticking out the right angle style. And then this has a petriometer. You can change the current going through the sensor. I know. And then, you know, I was thinking because I just did this Neo RGB, maybe folks want to like, you know, just make something Neo pixel, like a single LED that doesn't need the high current past transistors. So I made a breakout for this WS2811F chip. It's like basically like a Neo pixel on a chip. You can connect any LED you like. And I made a little boardboard. Friendly friend. Right. That's top secret, really. Yeah, it's top secret. Okay.
