Libre, ergonomic, polymorphic: a single PCB for many possible layouts.
3×6, 3×5, hummingbird, and everything in between.
This keyboard is mostly Nuclear-Squid’s work:
- hardware design (KiCad and Ergogen sources)
- ZMK firmware implementing the Selenium keymap
If you want to build or submit a case for this keeb, here’s the FreeCAD source:
- onboard RP2040 (left) and I/O expander (right)
- splittable in two (I²C communication over a TRRS cable)
- splittable outer columns
- hotswap sockets
- optional Circle Trackpad
- optional rotary encoders
