I rarely have time to build things I write about, but I really wanted to try this little computer. The parts sat partially assembled for a while and then a PCB came out for it.

While the Arduino family of boards connect to your computer using a USB virtual serial port, the ATmega ones have an actual serial connection on-board.

So yes, you can use ChatGPT to write Arduino drivers, but the catch is that this approach is only going to be possible if you are already extremely good at writing them yourself.
