FLIGHT CONTROLLER H7A3-WING
STM32H7A3RIT6 280MHz, ICM42688P, SPL06-001, OSD, 6x UARTs, 1x I2C, 1xCAN, 11x PWM outputs, BEC5V, BEC9V
The Matek H7A3 Wing Flight Controller is a powerhouse autopilot solution built for fixed-wing aircraft, VTOL platforms, and complex UAV builds that demand high output counts, rock-solid sensing, and serious power handling. Designed to run ArduPilot firmware, it combines an ultra-fast STM32H7A3 processor with a modern ICM42688P IMU, SPL06 barometer, onboard OSD, and MicroSD blackbox logging—making it ideal for long-range, survey, mapping, and experimental aircraft projects.
With support for 3–6S LiPo input, three independent high-current BEC rails, and an integrated digital power monitor rated for up to 164A burst, the H7A3 Wing removes the need for external PDBs or current sensors in most builds. Eleven PWM outputs, six UARTs with inversion, CAN, I2C, and multiple ADC inputs give you huge flexibility for servos, ESCs, GPS, telemetry radios, airspeed sensors, gimbals, and digital video systems.
The board uses a multi-layer stacked design with cover plates and includes a USB-C / buzzer extender for easy bench setup. Standard 30.5 × 30.5 mm mounting keeps installation straightforward in most airframes.
