Overview
A high-performance H743 FPV flight controller. It is the main control board for a multirotor: it runs Betaflight/AP/INAV firmware, reads dual gyros and barometer, drives ESC/PWM outputs, and powers/controls VTX and camera accessories.
- STM32H743 FPV flight controller
- 12-28 V DC / 3-6S LiPo input range
- Dual BEC outputs: 5 V/4 A and 12 V/2 A
Hardware revision
Check the sensor markings and component layout on your board against the manual and diagrams below.
Setup notes
- Use the product wiring diagrams for DJI O4, ELRS, analog VTX, and other peripherals.
- Firmware is compiled by FlyingRC and may not appear in the public Betaflight target list.
- Choose the firmware path that matches your build, then verify board target, wiring, and sensor orientation before flight.
- Input: 12-28 V DC / 3-6S LiPo.
- Recommended: 5S/6S LiPo or 4S LiHV for stable VTX BEC margin; for 3S/4S ensure VTX BEC input is above 12.8 V.
- Dimensions: 36.6 x 36.6 x 7.45 mm; weight about 9.3 g.
- Firmware target: FLRC H7D; factory default Betaflight 4.4.2.
- ArduPilot target branch: FlyingRC-Official/ardupilot add_FlyingRC_H7D_target.
- Betaflight config branch: FlyingRC-Official/betaflight-config Add-FlyingRC-H7D-Config.
- Check battery voltage before relying on the 12 V VTX output.
- ArduPilot SERIAL numbers do not correspond one-to-one with UART labels.
