#updi — Public Fediverse posts

I wanted to try out a few new things. So, I designed a development board for the AVR DA #microcontroller, the 32 pin #TQFP looked like something I'd be able to hand solder. I really like #UPDI from the ATtiny814. This is the result, my first four layer boards, first time with logos and an image. The image of #Frieren was a bit too small, though. Manufactured by @aislerhq again.

I've been playing with the newer ATtiny IC recently and decided it was time to recreate #AVRFT234 (my small AVR ISP programmer using an #FTDI #FT234XD) as a low voltage #UPDI programmer. I'm calling it the #UPDIFT234 😄 .
