The iFlight BLITZ H743 Pro (China) is an H743 flight controller with 12 motor outputs for larger multicopters running ArduPilot, target BlitzH743Pro. It is meant for platforms that drive more than the usual four motors, such as hexacopters and octocopters, and brings the connections of a small autopilot.
The STM32H743 runs at 480 MHz, the gyro is an ICM42688, and the barometer is a DPS310 (v1) or an SPA06 (v2). ArduPilot is the intended firmware. Interfaces are 7 UART and USB, 13 PWM (12 motor and LED) and an AT7456E OSD; two BECs supply 5 V at 2.5 A and 12 V at 2 A. The input voltage is 2S to 8S LiPo. The board measures 36.9 × 52 mm with a hole pattern of 30.5 × 30.5 mm and weighs 35 g.
A multi-motor platform easily weighs more than 900 g and then falls out of the small classes; from 25 kg take-off mass the operation belongs in the specific category. ArduPilot includes geofence and failsafe functions that can serve as the basis of a geo-awareness function.
When selecting, note the revision: versions 1 and 2 differ in the barometer. At 35 g the board is heavier than a pure controller in 30x30 format, but it carries the outputs for twelve motors. Wear shows at solder pads and the USB socket and in the damping; before ArduPilot updates the parameter file is saved, after modifications the accelerometer and compass are calibrated.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Ask about parts availability for this build year — the running costs hang on it.
