FlyingRC H7D H743 FPV Flight Controller
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.
Best used for
- FPV builds needing H743 processing headroom.
- Pilots using DJI O4, ELRS receiver, analog VTX, LEDs, buzzer, and multiple UART peripherals.
- Users who want onboard 5 V and 12 V BECs with switchable VTX power.
Key features
- STM32H743VIT6 MCU, dual ICM-42688-P gyros, and DPS310/DPS368 barometer.
- Analog/HD OSD, 7 UARTs, 9 PWM channels, I2C, ADC RSSI, LED, buzzer, Type-C USB, and 128 MB onboard flash.
- Dual BECs: 5 V/4 A for devices and 12 V/2 A for VTX/camera.
- Switchable onboard 12 V BEC via PINIO1/User1 to reduce VTX overheating during bench testing.
Setup / wiring 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.
Check before use
- Check battery voltage before relying on the 12 V VTX output.
- ArduPilot SERIAL numbers do not correspond one-to-one with UART labels.
Key specs
- 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
