Matek H743-Slim V4 Flight Controller - 30x30mm

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.

What is new on the H743-slim-V4

• Increase the output current of BEC5V from 2A to 2.5A, and raise the filtered VBAT current from 1A to 2A.
• Add TVS protection on Input voltage
• Add protections on more MCU I/O.
• Replace DPS310 with DPS368(environmentally protected against water (IPx8), dust & humidity)
• Other functions, Pins/Pads layout are same as previous board version.
