The RPBoy Mini was designed as an RP2040 based alternative to the Arduboy Mini. While it can be used to run some Arduboy games with code modification, I am adding it here as it can also run GP2040-CE just fine.
Please note that none of the converted Arduboy code will be posted here.
I do have plans to make a simple case for this, and may work on the design a bit in the future. I have no plans to make it powered by battery.
This is a very simple board. It has an RP2040 SuperMini, 0.96" OLED and a few tac switches on it. There is no battery on it and I have no plans to add a battery / charging circuit to it, this will just be for use plugged in.
Parts needed:
- The PCB in this repo
- 1x RP2040 SuperMini (usually gotten from somewhere like AliExpress) [the Waveshare Zero will not work!]
- 1x 0.96" OLED
- 6x SMD-4P,5.1x5.1mm 1.5mm tac switches
