Product overview
The XJSF H743 is a flight controller from Shenzhen Xingji Sufei Technology Co., Ltd., whose hardware range includes components for racing and professional FPV drones. It supports PX4 firmware and uses an STM32H743VIT6 microcontroller running at 480MHz, with 1MB of RAM and 2MB of flash memory. Its sensor configuration includes BMI088 and BMI270 gyroscopes and accelerometers, a QMC5883P magnetometer and an SPA06 barometer. An AT7456E chip provides the controller's on-screen display hardware.
For integration, the H743 provides eight UARTs, eight PWM outputs and one I2C interface. PWM channels 1–8 support DShot and bidirectional DShot. Other connections include current ADC sampling, SWD debugging, a buzzer interface, an LED strip interface, a Type-C port and a TF card slot. The black PCB measures 36 × 36mm, weighs 9g and has 30.5 × 30.5mm mounting-hole spacing with 4mm hole diameters. Its specified VBAT input range is 2–6S (6–27V), with BEC outputs of 12V at 3A and 5V at 3A. The specified operating temperature range is -35 to 85°C.
