Description

Matek H743-SLIM V4 flight controller is based on a powerful 480MHz STM32H743VIH6 processor and is characterized by excellent quality and performance. It is equipped with two ICM42688P gyroscopes for high-precision control while driving. Powered by 2-8S LiPo batteries with an input voltage of 6-36V. Provides a wide range of connectivity with 7 UARTS ports, 13 PWM outputs, 6 ADC outputs, 2 I2C ports and 1 CAN port. It has one 5V BEC and a switchable 5V/Vbat output for powering a camera or video transmitter. It uses a USB Type-C connector for setup and supports microSD cards for recording logs in Blackbox. It has wide compatibility thanks to the support of ArduPilot, BetaFlight and iNAV firmware.

The main differences from other versions are the presence of a more powerful BEC with an output current of 2.5A, an increase in the filtered current Vbat to 2A, and the replacement of the barometer with a more waterproof DPS368. Also, an additional TVS-diode for the input voltage was added and the protection on the microcontroller I/O was strengthened.
