 All right, lady, what is this? Hey, happy new year. This is a design that actually I did a while ago and I made a mistake. I accidentally placed a like 100 ohm resistor instead of 100K resistor. So these were remade, repaired. So this is a TPS61040, which is a little boost converter I use for OLED boards to generate the 12-volt bias. And I thought it would be nice as a little breakout board so you can just give it like 2 to 6 volts. And it'll give you 12 volts at like 40, 50 milliamps or so. So not enough to like drive a ton of LEDs, but enough just to kind of like, oh, you know, I have a 3.3-volt logic thing. I need 12 volts. So this is the tester. I've got a little load switch, 120 ohms, and a resistor divider. And I just use this Arduino code to test it. And it's passing. So we're going to get this into the shop real soon.
