Flight Controller H743-WING V3
Description
1. Product Summary
1.1. Product Description
The Matek Systems H743-WING V3 is a high-performance flight controller designed for fixed-wing, VTOL, and aircraft platforms. It features the powerful STM32H743VIT6 microcontroller running at 480 MHz with dual IMUs for exceptional flight stability and redundancy. The integrated Power Distribution Board (PDB) supports high currents and a wide input voltage range (3–8S LiPo), making it ideal for large UAVs and long-range aircraft. This controller is optimized for ArduPilot and other open-source autopilot firmware stacks.
1.2. Product Features
- MCU: STM32H743VIT6, 480 MHz, 1 MB RAM, 2 MB Flash.
- Dual IMUs: ICM42688-P + ICM42605 for enhanced stability and redundancy.
- Barometer: DPS310 digital pressure sensor.
- Integrated Power Distribution Board (PDB) with up to 90 A continuous current handling.
- Supports 3–8S LiPo (8–36 V input) with TVS protection.
- 7 UARTs, 13 PWM outputs, 2 I²C buses, 1 CAN port, and 6 ADC channels.
- microSD slot for Blackbox data logging.
- Integrated OSD for analog video systems.
- Dedicated BEC outputs: 5 V, 9 V, and 12 V for cameras and VTX.
- Ideal for ArduPilot-based fixed-wing and VTOL platforms.
1.3. Applications
- Fixed-Wing Aircraft: Long-range FPV planes and autonomous UAVs.
- VTOL / Hybrid Aircraft: Dual-mode aircraft needing multiple servo outputs.
- Survey & Mapping Drones: Systems requiring high-precision flight and telemetry.
- Research / Industrial UAVs: Platforms needing redundant sensors and high input voltage capability.
