LUX-H7 has betaflight firmware preloaded for QC
BetaFlight Target MATEKH743 is supported since 4.3, pls download BetaFlight firmware 4.2.x from our website.
It is highly recommended to use STM32CubeProgrammer to erase MCU and upload ArduPilot firmware.
If H743 MCU will not initialize with Ardupilot firmware, Pls follow this wiki to fix

The configured feature will be triggered when the auxiliary switch’s pwm value becomes higher than 1800. It will be deactivated when the value falls below 1200.
Check the pwm value sent from the transmitter when the switch is high and low using the Mission Planner’s Initial Setup >> Mandatory Hardware >> Radio Calibration screen.
If it does not climb higher than 1800 or lower than 1200, it is best to adjust the servo end points in the transmitter.
BetaFlight PINIO
If using DJI FPV Remote Controller and Air Unit is powered by 9V, DO NOT enable 9V power switch, just keep it ON by default.

PWM1~PWM13 are Dshot and PWM capable. However, mixing Dshot and norm al PWM operation for outputs is restricted into groups,
ie. enabling Ds hot for an output in a group requires that ALL outputs in that group be configured and used as Ds hot, rather than PWM outputs.
If servo and m otor are m ixed in same group, make sure this group run lowest PWM frequency according to the servo specification.
ie. Servo supports Max. 50Hz, ESC must run at 50Hz in this group.
