Description:
H743-WING v3 is a refreshed design of the popular H743 Wing flight controller from Matek ICM42605, some revised connectors and component layout to make the board even better than before. Best of all this flight controller can be used with Betaflight, Inav and Ardupilot.
Update to V3
H743-WING-V2(Purple PCB) has been updated to V3(Blue PCB) since end Apr.2022.
IMU ICM42688-P(V3)+ICM42605 instead of MPU6000(V2)+ICM42605
Same functions, layout, wiring schematic & I/O mapping.

Other Notes
ArduPilot
- H743-WING-V3 with ICM42605 is supported by ArduPilot 4.1 latest or newer,
- ICM42605 is defined as first IMU (IMU0) , MPU6000 is the 2nd (IMU1).
- Current sensor range is 220A on H743-WING-V2, make sure you set the BATT_AMP_PERVLT to 66.7
- It is recommended to use STM32CubeProgrammer to erase MCU and upload firmware.
- Known issue and solution, H7 will not initialize with Ardupilot firmware
INAV
- Current sensor range is 220A on H743-WING-V2, make sure you set the Current Meter Scale to 150
- IMU ICM42605 is supported by INAV3.0.2 or higher.
- MPU6000 is the first IMU(IMU0, default), ICM42605 is the 3rd IMU (IMU2) in INAV MATEKH743 target.
- If you want to try the new ICM-4 series of IMUs. download inav_3.0.2_MATEKH743.hex
- set gyro_to_use = 2
- set acc_hardware = icm42605
- save
- If you stick with MPU6000 only, H743-WING-V2 works with stable version 3.0.x downloaded from configurator also.
- Known issue, SD card and MSC mode for H743 is not implemented.
Others
- If the ESCs you are using don't have enough capacitors integrated, low ESR electrolytic capacitor is required for reducing ESC noise.
