Matek H743-Slim V4

Matek H743-Slim V4 is a high-end flight controller designed for freestyle and long-range drones powered by 2–8S LiPo batteries. It offers wide compatibility with Betaflight, iNav, and ArduPilot firmware. The board is built around the powerful H743 processor combined with two ICM42688P gyroscopes for precise motion data and a DPS368 barometer for altitude measurement. For analog video, it includes an OSD chip and a microSD slot for Blackbox logging.

The board provides extensive connectivity: 13 PWM outputs (including LED), 7 UARTs, 2 I2C buses, 1 CAN port, and 6 ADC inputs for voltage, current, RSSI, airspeed, or secondary voltage/current measurement. Through the Vbat2 pad, it can monitor voltages up to 69V. It supports connecting two analog cameras with switching capability. The board also integrates a 5V/2.5A BEC and a switchable 5V or VBAT output (up to 2A) for powering a camera or VTX. A USB-C connector is available for configuration, along with pads for an external USB connector for easier access. All components are mounted on the top side, leaving the bottom flat for a low profile and easier installation.

Compared to the previous version, the board features a stronger BEC, a filtered VBAT output with higher current capability, an added TVS diode at the input, and extra MCU I/O protections. The DPS310 barometer has been replaced with the more water-resistant DPS368.
