 All right, Lady, what's this? This is an AT Tiny 817 Breakup Board, which we stock. And this is my UPDI friend. UPDI is a one wire programming interface for AT Tiny chips, modern AT Tiny chips. It's nice because you only need one wire. It's compact. It's easy. You just need a USB-CO converter. So I've got this board that I designed. It's got a three or five volt logic and power selection switch. It's got a powering and UPDI in ground. Some silkscreen on the back. You can use a JSTSH cable to make wiring nice and easy. And then I designed a tester for it using an RP2040 because we have native USB serial with bit-banging available on any other pins. So I've got this USB host port, which will enumerate and connect to the onboard USB serial chip. And then when I put it here, tests that data is going in and out of the UPDI pin correctly. So this passes test. Very nice. And it's going to be ready to go in the shop soon.
