Lluis Merlos Pieri aka SRgrezz/llmerlos shared PICCTRL 0xLM, a split ortho with thumb arcs and on-board CH559L MCU.

I wanted to make a compact keyboard by using the minimum surface for the keys with all the components underneath them while no increasing the height of the overall keyboard.

Specs

  • 42 keys (6x3+3 per half)
  • Choc V1 spacing
  • CH559L FAK powered
  • Direct pin with ESD and over-current protection (schematic)
  • 3D printed case
  • PCBA ready*

  • Some known issues: USB part is a bit misplaced and requires trimming the legs, it is for 0.8mm PCB instead of 1.6mm PCB.
  • Pic:
