I've been trying to get a Pi Zero 2 for a while. Can't find it anywhere. I can't seem to make any alternatives for the project work due mostly to a lack of support/docs/libraries and my own lack of expertise. In theory it should work with ESP32 (first preference), Teensy 4.1, and possibly a Banana Pi M2 Zero. I got it to basically work on an old Pi Zero, but it was laggy due to xwindows and only one slow core. Maybe I can figure out how to slim it down more, but I doubt it. I guess I'm waiting an unknown time for a Pi Zero 2...
