3×6, 3×5, hummingbird, and everything in between.
This is just the public web page of the project, which is mostly Nuclear-Squid’s work:
- hardware (KiCad and FreeCAD sources)
- ZMK firmware implementing the Selenium keymap
- 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
