The Matek H743-WING V3 flight controller uses the most advanced and powerful H743 processor, operating at 480MHz with 1Mb of RAM. The board features a new CAN port to support future UAVCAN peripheral devices.

The Matek H743-WING works with ArduPilot, BetaFlight, and iNAV firmwares.

What's new in H743-Wing V3?

• Instead of two MPU6000(V2)+ICM42605 gyroscopes, a new ICM42688-P(V3)+ICM42605 gyroscope is used
• Compatible with new versions of ArduPilot plane 4.2.0+ and INAV 5.0+ firmwares
• PDB/current sensor moved from FC board to bottom plate
• 8A BEC moved from top board to bottom board
• JST-GH connector installed for CAN port instead of JST-SH connector
• Added JST-GH connector for I2C2 for plug and play connection with ASPD-4525 airspeed sensor

Recommendations

• H743-WING comes with Betaflight firmware pre-installed for quality control
• ArduPilot firmware supports the built-in DPS310 barometer starting from stable versions Plane-4.0.6 and Copter-4.0.4.
• Troubleshooting: H7 AutoPilot not initializing with Ardupilot firmware
• If you upload ArduPilot firmware to the controller via INAV / BetaFlight configurator. A known issue is that the upload process hangs at 50% if "full chip erase" is selected. It is highly recommended to use STM32CubeProgrammer to erase the MCU and upload the firmware. Official instructions from Matek
• Crossfire support only exists in the "latest" 4.1 version, not 4.0.x. If you upload the "latest" 4.1 version, set SERIAL7_PROTOCOL = 23, RSSI_TYPE = 3.
