keyboard1_final_result

Initial release of the PCB design for this split, 36-key keyboard.

Design goals:

  • PCB smaller than 100x100 mm2, so that it's cheaper to fabricate at various PCB fabricators.
  • Reversible PCB (use the same PCB for left/right halves).
  • Using the WeAct Studio MiniF4 "black pill" dev board.
  • Low profile (PCB + choc switches + bumpons).
  • Column-staggered arrangement of key switches.
  • Per-key RGB LEDs.

Errata:

  • Pins PA11, PA12, PB2 aren't suitable for use for GPIO on the MiniF4 board, since these are used for other things. This can be mitigated by jumping from PTHs underneath unused pins of the devboard.

  • The design of the circuit for the SK6812mini-e LEDs is invalid. i.e. the RGB LEDs don't work. The VDD the SK6812mini-e receive is from the 3V3 pin. This is insufficient to power the RGB LEDs. The DIN from A0 has the same 3V3 voltage, and so can't reliably signal the series of RGB LEDs.
