This GitHub repository serves as a backup and documentation hub for the AirBrain H743 flight controller.

All official information and product details are available on our website: Airbrain Product page

The AirBrainH743 is now officially supported by both Betaflight, ArduPilot and PX4, with the target added to their main branches. We also have beta firmware targets available for INAV, and a development framework on Platform IO (Arduino). This repository exists to provide a secondary reference location for hosting documentation, pinout diagrams, and firmware resources, to ensure the information remains easily accessible.

For the latest Ardupilot: https://firmware.ardupilot.org/Copter/latest/AIRBRAINH743/

For the latest Betaflight, click the dropdown list inside Betaflight configurator and select: AIRBRAINH743

The /datasheet folder contains the official datasheet and pinout diagrams for the AirBrain flight controller.

The '/firmware' folder contains backup binaries and source files related to the AirBrain target.

Please always use the official AirBrain firmware provided by the Betaflight or ArduPilot communities.

This repository is only for documentation and archival purposes.

Inside the firmware folder:

'/sourcecode' – Gear Up source files used for target creation

'/bin' – precompiled binary files that can be flashed to the AirBrain

These instructions are only for when you would like to build PX4 AirBrainH743 target yourself. If you would just like to install PX4 on the board, please see the '/firmware/PX4/bin' folder that contains PX4 firmware files for the AirBrainH743.

Following instructions expect you have a working PX4 development environment. Copy the contents of '/firmware/PX4/sourcecode' inside your PX4 environment under 'gearup/airbrainh743'.
