Creators! Feel free to tip me off about your keyboard related projects to bring them to 120K readers.

Dmitry Belousov aka ProgressiveNoise shared a split keyboard PCB and case, inspired by the Cantor.

This keyboard is compact, reliable, and relatively easy to build. It is diodeless, the protection circuit is optional. Only the TH USB-C connector could be an annoyance for an inexperienced builder, but that’s it. Everything else should be smooth – Dmitry.


  • 42 keys (3x6+3)
  • MX, hotswap
  • diodeless
  • USB-C for interconnection
  • Pico footprint (RP2040)
  • KMK
  • case
