PotatoPi Overvieww

PotatoPi is a custom RP2040-based devboard that can be used for lots of cool hardware and software projects. It follows the same pinout as the Raspberry Pi Pico and is fully feature-compatible..

It will also include headers soldered on.

  • Features
  • 16MB onboard flash memory
  • Convenient reset button for easy flashing
  • Custom PotatoPi artwork on both sides of the PCB
  • All components hand soldered (no PCBA)

I made this to get back into hardware and to redeem myself from my last project. I also wanted to try out SMD soldering. The board will use a hot plate to do most of the reflow work and then an iron to fix any mistakes and add the ehaders.s.
