MATEK H743 WING V3 Flight Controller
The Matek H743 WING V3 Flight Controller is a powerful and versatile control board from Matek for fixed-wing aircraft. Category: Drones & Quadcopters > Stacks (FC+ESC). This module combines a high-performance STM32H743VIT6 processor (480MHz) with 1Mb of RAM and a total memory of 2Mb, ensuring stable operation of complex firmware and autopilot functions for amateur and professional projects.
Key Advantages and Updates in V3 Version
- Updated main gyroscope ICM42688-P (V3 version) instead of MPU6000 (V2) paired with ICM42605 for increased reliability and measurement accuracy.
- Support for modern firmware: Ardupilot plane 4.2.0+ and INAV 5.0+.
- Optimized layout: PDB/current sensor elements and 8A BEC are moved to the bottom PDB board for easier installation and improved cooling.
- More reliable CAN connector — JST-GH instead of the previous JST-SH, increasing compatibility with UAVCAN peripherals.
- Added JST-GH connector for I2C2 for plug-and-play connection of the ASPD-4525 airspeed sensor.

PDB Board Specifications for MatekSys H743 WING
The controller comes with a PDB board, which is responsible for power delivery and accurate measurement of battery and current parameters. The PDB features wide power inputs and TVS protection, making it a reliable part of your model's electrical system.
| Parameter | Value |
|---|---|
| Input Voltage Range | 9 ~ 36V (3 ~ 8S LiPo) with TVS protection |
| ESC Outputs | 2 |
| Current Sensor | 132A, 3.3V ADC (scale 250 in INAV, 40 A/V ArduPilot) |
| Voltage Sensor | 1:10 (scale 1100 in INAV, BATT_VOLT_MULT 11.0 in ArduPilot) |
| Current Sense Resistor | 60A continuous, 132A burst |
Integrated BECs for Peripheral Power
The module offers several stabilized outputs for powering the flight controller, receiver, camera, VTX, and servos without additional converters, simplifying installation and reducing system weight.
| BEC | Purpose | Characteristics | Max Current |
|---|---|---|---|
| 5V | FC, receiver, OSD, FPV camera, buzzer, LED module, GPS, AirSpeed sensor | Stabilized | 2A (max. 3A) |
| 9V/12V | Video transmitter, FPV camera, LED module | 12V option with jumper | 2A (max. 3A) |
| Vx | Servos | 5V by default, 6V or 7.2V with jumper | 8A (max. 10A) |
| 3.3V | Baro/Compass module and Spektrum RX | Linear regulator | 200mA |
Firmware Compatibility
The board comes with Betaflight factory firmware but is fully compatible with several flight stacks for various tasks and configurations:
- ArduPilot: Matek H743 WING V3 Ardupilot plane 4.2.0+ and Copter-4.0.4+ are supported, including the built-in DPS310 barometer.
- INAV: Compatible version 5.0+ with board ID MATEKH743.
- BetaFlight: Supported with board ID MATEKH743.
Attention: When flashing ArduPilot via the INAV/BetaFlight configurator, a hang at 50% may occur when selecting full chip erase. It is recommended to use STM32CubeProgrammer for full MCU erase and flashing according to official Matek instructions.
