Matek SystemsMatek Systems - Flight Controller H743-WING V3

**UPDATE** This is H743-WING Version 3

• 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.

 *** V1/V2/V3 share same ArduPilot/INAV Target ***
