Description The Mateksys Flight Controller H743-SLIM V4 designed for RPAS and FPV systems demanding powerful performance, precision, and sleek integration. Built on the STM32H743VIH6 microcontroller clocked at 480 MHz, it features 1 MB of RAM and 2 MB of flash memory, ensuring ample resources for advanced firmware and functionalities (ArduPilot, Betaflight, and soon iNav). It includes dual ICM42688P IMUs, providing highly accurate inertial data and redundancy. The barometer is an Infineon DPS368, offering improved altitude measurement performance. Visual overlays are handled by the integrated AT7456E OSD, with Blackbox logging facilitated by a microSD card slot V4 improvements 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) Upon receiving your FC,please connect to USB and calibrate before continuing to build and solder to it.
