H7D H743 FPV Flight Controller

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

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.
