The Kiibohd Controller

This is the main Kiibohd Firmware. In general, this should be the only git repo you need to clone. The KLL git repo is automatically cloned during the build process.

Please refer to the KLL repo or kiibohd.com for details on the KLL (Keyboard Layout Language) Spec.

Official Keyboards

The Kiibohd firmware supports a lot of other keyboards, but these are more obscure/custom/lesser known.


Compilation is possible and tested on Windows/Linux/macOS. However, the recommended method is using a Dockerfile.

Then, once you have a docker environment, you can select a build script here.

To compile natively for your platform, refer to the wiki.

Supported Microcontrollers

Adding support for more microcontrollers is possible. Some considerations for minimum specs:

  • ~16 kB of SRAM
  • ~64 kB of Flash

It's possible to port chips with lower specs, but will be more effort and have fewer features.

General Code can be found in Lib.


A custom bootloader (based off of McHCK) is available. This is only necessary when assembling a keyboard with a blank MCU or if you're attempting to re-flash your bootloader (requires external tools).
