KMK is a keyboard firmware written and configured in CircuitPython, supporting single-piece and split mechanical keyboards with features like chainable keys, macros, RGB lighting, and Bluetooth HID. Configuration lives in a single Python file on the microcontroller, editable without flashing tools.

Use cases

• configure a custom mechanical keyboard in Python
• build a split keyboard with Bluetooth wireless connection
• add RGB underglow and LED backlights to a keyboard
• create tap-dance and macro keys on a keyboard
• edit keyboard keymaps on the go without flashing firmware

When to choose

• you want Python-based keyboard configuration instead of C/QMK
• you use CircuitPython-compatible microcontrollers like RP2040, SAMD51, or nRF52840
• you want beginner-friendly firmware with a single config file
• you need wireless split keyboard support via Bluetooth

When to avoid

• you need actively maintained firmware with timely bug fixes
• your board only runs QMK/ARM C toolchains without CircuitPython support
• you need features beyond KMK's supported modules
