The popular open source Quantum Mechanical Keyboard (QMK) Firmware supports Microchip ATmega32U4 and therefore it is easy to use as the default firmware for ANAVI Macro Pad 8. However, it is technically also possible use ANAVI Macro Pad 8 as a development board and upload Arduino sketches compatible with Arduino Leonardo through Arduino IDE or PlatformIO. Many popular development boards such as Arduino LeonardoSparkFun Pro MicroTeensy 2.0Olimex eduArdu also use ATmega32U4.
