If it ain't broke, don't fix it. The boards run Betaflight, AM32 and ExpressLRS
Hardware is CERN-OHL-S-2.0: fork it, sell it, but publish your changes. Firmware is not part of these repositories; the boards run the upstream projects above under their own licences.
OSHWA certified open source hardware: OpenFC-Lite, OpenFC-Lite-Mini, OpenESC-20x20, OpenESC-30x30, and OpenRX Lite, Lite-UFL, Mono and Gemini.
