MReavley published the CyberSlice keyboard, an evolution of his Slice36.

This 36-42 key split (breakaway outer column) is powered by an onboard RP2040 and has footprints for magnetic pogo connectors with the intention of adding further functionality.

This was my first time working with a microcontroller directly when laying out the PCB, it took a lot more time but I'd say it was worth it as a learning experience – MReavley.

The custom 3D-printed case is held together by 3mm neodymium magnets (STLs in the repo).

Obviously, the name is derived from his previous project, with a well-deserved prefix:

[…]What I thought would make it deserve the "cyber" prefix, [is] a modular connector (using the magnetic pogo connectors) on each side for additional accessories (pointing devices, oleds etc through 3.3V, GND, and 8x GPIO 2 of which are analog capable), although I've not really had the time to work on that[…] – MReavley.

Features

  • Reversible PCB designed for PCB assembly services
  • RP2040 per side, with 16MB of flash
  • Laser cut aluminum plate, custom designed 3D printed case with magnets
  • Footprints for magnetic pogo connectors on each side
  • Breakaway tabs convert the layout from 42 to 36 key
