Ximi prototype

Ximi is a split keyboard prototype with dual trackball/trackpad support – by Sadek Baroudi.

Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

This is a prototype! The Ximi V1 fixed some issues and ended up as a quite different keyboard (e.g. on-board controllers).

Ximi is another project by Sadek Baroudi / Fingerpunch, this time a split keyboard with dual trackball/trackpad support, and Xiao RP2040 controller boards (don't forget the Seeed keyboard competition).


  • Xiao RP2040
  • Haptic feedback
  • Audio buzzer
  • 42 or 36 key (outer columns can be broken off)
  • Dual cirque support
  • Dual trackball support
  • Per key RGB support
  • Hotswap MX and Choc
  • 3-way thumb wheel (below thumb cluster)

As of my understanding, the 3-way "thumb wheel" is rather a 3-way switch (this one).

You can flick the switch left, right, or you can press it. Each of those actions act and are defined just like a regular keyswitch in QMK – sadekbaroudi.

The firmware still needs some finishing touches, but the case files have been already published:

I'm working on an issue in the firmware, so by the time I get everything sorted and publish proper, I'd guess a couple of weeks to a month – sadekbaroudi.

Cases available in the fingerpunch Git repo:
