H743 Flight Controller Reference Images

This guide explains the ArduPilot configuration and tuning workflow for beginners and covers the complete setup process for installing an AeroEgg AET H743 Basic fixed-wing flight controller in a fixed-wing FPV aircraft.

The AeroEgg AET H743 Basic fixed-wing flight controller uses a stacked design comprising a Bluetooth top board, flight controller, and power BEC board. It features an STM32H743VIT6 MCU, dual ICM42688 accelerometer/gyroscope sensors, an SPL06 barometer, an integrated AT7465E OSD chip, and an onboard Bluetooth telemetry link module.

It provides 8 UART ports, 12 PWM signal outputs (grouped by timer as 12, 37, and 8~12), and 2 SDA I2C parallel peripheral interfaces;

The onboard servo BEC provides up to 10A continuous current at 5V.

The 5V BEC provides 4A continuous output, sufficient to power 5V UART peripherals.

The 9V BEC provides 2A continuous output, sufficient to power a high-power video transmitter. The image above shows the flight controller power board. When soldering the power leads, the two ESC+ pads may be connected together (optional); the two ESC- pads and BAT- may also be connected together (optional).
