The former Matrix and Discord rooms once linked to in this README are no longer officially supported, please do not use them!
- Fully configured through a single, easy to understand Python file that lives on a "flash-drive"-esque space on your microcontroller - edit on the go without DFU or other devtooling available!
- Single-piece or two-piece split keyboards are supported
- Chainable
keys such as
KC.LWIN(KC.L)to lock the screen on a Windows PC - Built-in Unicode macros, including emojis
- RGB underglow and LED backlights
- One key can turn into many more based on how many times you tap it
- Bluetooth HID and split keyboards. No more wires.
KMK requires CircuitPython version 7.0 or higher. Our getting started guide can be found here.
Please have a look at the contributing document, where you can find details about the workflow and code style. If you have specific questions feel free to ask in the KMK development stream on zulip.
