With full compatibility across all major open-source flight stacks—Betaflight, ArduPilot, PX4, and INAV—the AirBrainH743 is a truly firmware-agnostic platform. At its core is the cutting-edge STM32H743 MCU, enabling synchronized clocking between the processor and the ICM-42688-P IMU. This architecture delivers ultra-low latency and unprecedented noise reduction, unlocking flight performance that surpasses conventional designs. Built with rigorously selected components, including isolated power rails for the IMU and industrial-grade sensors, AirBrainH743 is engineered to perform reliably in demanding environments where precision and robustness are non-negotiable.

Firmware
Betaflight firmware
For Betaflight, please flash the latest firmware using the Betaflight Configurator or the Betaflight app (chrome, chromium, edge). This gives you the newest stable build for your AIRBRAINH743 flight controller target. Betaflight’s flasher can detect the board and build the correct firmware image for you.
As a backup, you can download a pre-built Betaflight image for AirBrain here:
Tip: In Betaflight Configurator, go to “Firmware Flasher”, choose target: AIRBRAINH743, load firmware (online), then “Flash Firmware.”
ArduPilot firmware
For ArduPilot, we recommend flashing the latest stable build for your airframe and autopilot board using the official ArduPilot tools, Mission Planner (Windows) or the ArduPilot Firmware Server. These tools automatically detect your hardware, select the correct target, and handle the flashing process for you.
If you need to manually flash or keep an offline copy, you can grab our reference ArduPilot build for AirBrain here:
In Mission Planner: go to “Install Firmware”, pick your vehicle type (Copter / Plane / etc.), then use “Load Custom Firmware” if you want to flash this manual file.
Developers or advanced users can explore the hardware definitions, and firmware builds for this board on our GearUp AirBrainH743 GitHub repository
