A collection of keyboard and converter firmware projects built on the tmk_core keyboard library, targeting Atmel AVR and ARM Cortex-M microcontrollers. It is the original codebase from which QMK firmware was derived.
Use cases
- build custom mechanical keyboard firmware
- flash custom keymaps onto a DIY keyboard controller
- convert a vintage keyboard to USB
- program a Teensy or AVR-based handwired keyboard
- customize key behavior and layers on a programmable keyboard
When to choose
- you want the original, minimal TMK firmware stack for AVR or Cortex-M keyboards
- you are maintaining or porting older TMK-based keyboard projects
- you need a lightweight alternative to QMK with fewer features
When to avoid
- you want a modern, actively documented ecosystem with extensive community support - prefer QMK
- you need wireless, RGB, or advanced features out of the box
- you are not comfortable building and flashing C firmware yourself
