AeroEggTech AET-H743-Basic H743 Flight Controller for ArduPilot Fixed-Wing/VTOL, 10A BEC, Dual IMU

Overview

The AeroEggTech AET H743 Flight Controller (AET-H743-Basic) is a full-feature H7 autopilot designed for fixed-wing and VTOL builds, focusing on easy installation, complete I/O, and convenient tuning. It uses an STM32H743 (Cortex-M7) high-performance MCU and integrates core sensors and power features commonly needed for ArduPilot-style fixed-wing setups, while keeping expansion flexible via both direct plug connectors and high-compatibility Dupont headers.

Key Features

• STM32H743 MCU (Cortex-M7) with 480MHz clock, 2MB Flash, 1MB RAM (stronger processing headroom for complex missions)

• Dual IMU: ICM-42688-P x2

• High-precision barometer: SPL06

• Onboard OSD chip: AT7456E

• 8 UARTs for flexible peripheral expansion (GPS, telemetry, video link, receiver, ESC telemetry, etc.)

• Up to 13 PWM outputs (12 general + 1 LED channel) for motors/servos (fixed-wing, V-tail, delta, VTOL)

• High-power BEC / power system: multiple regulated rails, including adjustable high-current output up to 10A

• Built-in voltage & current sensing

• CAN interface

• Stacked (layered) design to reduce interference; includes heatsink / thermal-focused design

• Dual-mode Bluetooth serial: classic SPP + BLE; supports PC or mobile ground-station connection

• SD card slot supports up to 32GB

• Multi-firmware support (as indicated by the manufacturer’s materials)

Power & Anti-Interference Design

The AET-H743-Basic uses a stacked layout and module separation to reduce interference. The power system is designed for practical aircraft wiring, supporting multiple high-power BEC paths, including a servo BEC up to 10A with adjustable voltage, plus dedicated regulated rails for peripherals. This layout is intended to improve stability when combining power electronics and sensitive sensors.

Bluetooth + USB Tuning / Firmware Flashing

• Dual-mode Bluetooth serial (SPP + BLE) supports connecting to PC or mobile ground stations.

• Also supports USB parameter tuning and USB firmware flashing.

• The materials indicate: hold the BOOT button while powering on to enter DFU firmware flashing mode.

Connectors & Expandability

The design includes common “direct plug” connectors and also Dupont header options for custom wiring. A dedicated GPS/compass connector is included in the ecosystem, and the board exposes extensive MCU pins to reduce “not enough interfaces” issues on complex fixed-wing/VTOL builds.

What’s Included

• Main controller board

• Power board

• Bluetooth daughterboard

• USB small board

• Pin headers: 2×11, 2×4, 3×8, 1×4 short female header

• SH1.0 / GH1.25 cables

• Vibration damping balls + vibration pad

• Nylon standoffs

• Bullet connectors (“banana plugs”)

• Screws

• Heatsink

Applications

Ideal for ArduPilot fixed-wing and VTOL builds that need lots of serial ports and clean integration for GPS, telemetry, video link, Bluetooth ground station, and ESC telemetry. The AeroEggTech AET H743 Flight Controller is also suitable for users who want a compact H7 autopilot with dual IMU, SPL06 barometer, AT7456E OSD, and high-current BEC capability.
