EUnify AirBrain H743 is a powerful flight controller for drones, designed for maximum reliability and compatibility with Betaflight, ArduPilot, PX4, and INAV. The flight controller is manufactured in Belgium. The components on the board are sourced from the EU, USA, or Japan, so no part of the board is imported from China.
AirBrain H743 supports a power input range of 10–42V (3–10S LiPo) and is equipped with protection against reverse polarity and overvoltage. The flight controller features a STM32H743 microprocessor, an ICM-42688-P IMU unit, a magnetometer for measuring azimuth LIS3MDLTR, and a barometer DPS368 for measuring altitude. There is also a 128MB memory for data logging (Blackbox).
There are two BEC circuits – 5 V/2 A for accessories like GPS, receivers, or LED strips, and 10V/2.5A for powering cameras or video transmitters. For connecting peripherals, there are 7x UART, 8x PWM outputs for motors and servos, I2C and SPI buses. It also offers 2 analog inputs (VBAT, CURRENT) and an output for buzzer and RGB LED strips. It also includes a USB-C connector with IP68 protection.
The board is designed for a mounting standard of 20×20mm (M3) and has compact dimensions of 27×33×18 mm.
