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:

ATmega16U2 / ATmega32U2
ATmega16U4 / ATmega32U4
AT90USB64 / AT90USB128
AT90USB162

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

ATmega32A
ATmega328P
ATmega328

ARM

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

STMicroelectronics (STM32)

STM32F0x2
STM32F103
STM32F303
STM32F401
STM32F411
STM32F446
STM32G431
STM32G474
STM32L412
STM32L422
STM32L433
STM32L443

NXP (Kinetis)

MKL26Z64
MK20DX128
MK20DX256

Atmel ATSAM

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