Yes indeed, it does enable Pi5 support although we don’t recommend it unless you have a massive need for it.
The Pi5 generates heat and there isn’t enough room for a good heatsink, and definitely not for a fan.
Also the power button on the Pi5 interferes with the one on GoPiGo (but that can be worked around, just don’t use the power button on the Pi5).
I see I had forgotten to mention that this now all works on Trixie (and Bookworm but not older versions).
No wonder you couldn’t follow It’s all on me. Too tired after pushing this massive update.
it’s been tested for 3B+ and up, but I do believe the 2 would work too. However, it will not work on older versions of the OS. You do need to go with Trixie
And, yes, massive amount of work.
For anyone still troubleshooting, it can also help to verify the software versions on both the Raspberry Pi and GoPiGo, since a mismatch there can sometimes cause odd behavior. A clean update and reboot solved a similar issue for me.
