Matek H7A3-WING Flight Controller

The MatekSys H7A3-WING is a high-performance flight controller explicitly designed for fixed-wing UAVs, gliders, and long-range FPV aircraft. Built around a powerful STM32H7A3RIT6 280 MHz Cortex-M7 processor, it combines advanced sensor integration, flexible power regulation, and rich I/O to support complex flight control setups and autonomous missions.

FEATURES 

• High-Speed Processing: With a 280 MHz Cortex-M7 CPU, this board offers responsive and reliable control even under heavy computational loads.

• Precision IMU & Barometer: Equipped with the ICM42688P IMU for low-noise, high-bandwidth motion sensing, plus the SPL06-001 barometer for accurate altitude readings.

• Onboard OSD: Integrated AT7456E OSD lets you overlay telemetry—such as battery voltage or flight status—directly onto your video feed.

• Comprehensive I/O:

  • 6 UART ports (all with built-in inversion) for telemetry, GPS, receivers, and more

  • 1 I²C and 1 CAN interface to connect additional sensors or peripherals

  • 11 PWM outputs for servo control, making it ideal for complex fixed-wing or VTOL configurations.

• Digital Power Monitoring: Features a high-precision I²C power monitor with a 0.00025 Ω shunt resistor, capable of sensing 100 A continuous / 164 A burst, without calibration.

• Flexible Power Regulation:

  • Input voltage from 9 V to 30 V (3–6S LiPo)

  • Multiple BEC outputs: 5 V (2.5A cont / 3A peak), switchable 9V or 12V (2A cont / 3A peak), and a high-current “Vx” output (up to 8A continuous / 12A peak) to power servos and other peripherals.

• Data Logging: MicroSD slot for Blackbox logging to analyze flights and tune performance.
