JHEMCU GF30H743 STM32H743 FPV Flight Controller, Dual BEC 5V/10V, 30.5×30.5mm, Type-C

Overview

JHEMCU GF30H743 is an FPV flight controller built around an STM32H743 (480MHz) MCU, featuring dual onboard BEC outputs (5V and 10V) and a 30.5 x 30.5mm mounting pattern for FPV multirotor builds. It supports common receiver protocols (CRSF, SBUS, IBUS, DSM2/DSMX), analog OSD via AT7456E, and connection options for both analog VTX and digital HD VTX systems.

Details

Clear pad mapping for common FPV builds, including SBUS/IBUS on UART2, CRSF wiring, and analog or HD VTX connections.

Standard 30.530.5mm mounting keeps it drop-in compatible with many 5-inch frames while staying compact and lightweight.

The FC-only set includes the flight controller, an 8-pin SH cable, and soft mounting gummies for vibration isolation.

Stack option pairs the GF30H743 with a RuiBet 50A 4-in-1 ESC and the needed harnesses and power components for a clean build.
