Compatible Microcontrollers

QMK runs on any USB-capable AVR or ARM microcontroller with enough flash space - generally 32kB or more, though it will just squeeze into 16kB with most features disabled.

Atmel AVR

The following use LUFA as the USB stack:

Certain MCUs which do not have native USB will use V-USB instead:

ARM

You can also use any ARM chip with USB that ChibiOS supports. Most have plenty of flash. Known to work are:

STMicroelectronics (STM32)

NXP (Kinetis)

Atmel ATSAM

There is limited support for one of Atmel's ATSAM microcontrollers, that being the ATSAMD51J18A used by the Massdrop keyboards.
