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

Jon Mereria aka makgyber or jammerkiai published his Kiai Split, a wireless split keyboard sporting XIAO controllers.

The first xiao-based board i built turned out to have a few problems, so i decided to tweak a few things – jammerkiai.

The author fixed the key spacing, updated the PCB so both XIAO modules can be placed face-up, and kept the size of the PCB within 100x100mm.


  • 34-keys
  • low profile Choc v1
  • PCB dimensions <100100mm
  • Seeed Studio XIAO nRF52840
  • ZMK
