Matek H743 Wing Ardupilot Flight Controller

H743-WING has betaflight firmware preflashed (part of QC testing process).  But is fully supported by Ardupilot firmware

If you flash ArduPilot firmware via BetaFlight configurator. There is a known issue that flash process can freeze at 50% if “full chip erase” is selected. Disable full chip erase when flashing, then reset to default in Mission Planner after flashing.
