#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 😄 .

quad-rotary board is getting ready to stock 🔁🎛️💻🔄🔌

this seesaw board converts 4 rotary encoders to I2C for adding a ton of twists. like our other attiny8xx boards, we use a metro m0 to do the programming of the UPDI interface, then communicate over I2C to check each pin is not shorted or open. this will be in the shop soon so don't get your knickers in a twist! https://www.adafruit.com/product/5752
