The JHEMCU GH743AIO-HD is an all-in-one powerhouse, combining a Betaflight-ready STM32H743 flight controller and a 50A 4-in-1 AM32 ESC into a compact 33x33mm package. Designed for 3–6S FPV drones, this board features dual ICM-42688-P gyros for ultra-precise motion sensing, a 128MB blackbox for detailed flight logs, and full HD system support.

With its AM32 ESC firmware, it delivers 50A of continuous current per motor, making it perfect for demanding freestyle, racing, or cinematic builds. Complete with ELRS, TBS, SBUS, IBUS, and DSM receiver support, plus a Type-C port, buzzer pad, voltage and current sensors, and 25.5/26.5mm mounting compatibility, the GH743AIO-HD is ready to handle anything you throw at it.
