I encountered some challenges getting up and running with my Digispark ATTINY85 Micro USB dev board on Fedora 35, so I thought I would document it before I forget. The board was a few dollars and similar to this one:

The problems I encountered:
- The board uses the micronucleus bootloader https://github.com/micronucleus/micronucleus, which frees up pin 6 (
RESET
) for use but means I can't use the usual serial programmer. The instructions are for the Arduino IDE. - Arduino IDE no longer has a package maintainer on Fedora 35, so I couldn't install from the official repositories. It's available as a snap or flatpak, but I would prefer to install from the website.
