This is a 36 or 42 key with column stagger and kailh hotswap support (outer columns can be broken off).

Main features:

  • Hotswap only
  • Per key led support (SK6812 mini-e)
  • MX or choc on the same pcb!
  • A rotary encoder under each hand (support for the evqwgd001 and EC11)
  • In the center, supports a 34mm trackball or a cirque trackpad

To make this a complete kit, remember to also add:

  • faux fox keyboard v2 case or faux fox keyboard v3 case
    • The v2 case is intended for the v2 pcb, however the v2 cirque trackpad case is completely compatible with the v3 pcb
    • If you are using the trackball, you will need to get the v3 case
    • If you want to print yourself, case files are available in the fingerpunch github repo
  • hotswap sockets (4 sets if building a 36 key, 5 sets if building a 42 key)
  • a controller (see controller section below)

Optional components:

Controller support:

  • Nothing AVR is supported! So, do not try to use this pcb with a Pro Mico or Elite-C
  • STeMCell (tested, available as an add on)
  • Splinky (untested, but should work)
  • KB2040 (untested, but should work)
  • Blok (untested, but should work)
  • nice!nano for wireless (tested, but you are limited to ZMK firmware features)
