MATEKSYS H743-WING V3 Flight Controller

Designed for fixed-wing UAVs, VTOLs, and complex long-range builds, the Mateksys H743-WING V3 flight controller provides advanced processing capabilities via its 480MHz STM32H743VIT6 MCU. This V3 revision updates the sensor array to a dual-IMU configuration, with two ICM42688-P gyros for superior flight stability and redundancy. It retains the extensive I/O layout that makes it a standard for ArduPilot and INAV builders who require numerous servos, sensors, and peripherals.

Key features

• Dual IMU system: Two ICM42688-P gyros for reliable vibration handling and sensor redundancy.

• High-current servo BEC: Dedicated Vx step-down regulator adjustable to 5V, 6V, or 7.2V at 8A continuous for driving multiple servos.

• Extensive connectivity: Outfitted with 7 UARTs, 13 PWM outputs, dual I2C ports, and CAN bus support for complex peripheral setups.

• Integrated Blackbox: Onboard MicroSD card slot ensures you have virtually unlimited storage for flight logging.

• Video system flexibility: Built-in dual camera switcher and selectable 9V/12V 2A regulator for powering VTX and camera gear.
