FLIGHT CONTROLLER H743-SLIM V4
STM32H743VIH6, Dual ICM42688P, DPS368, OSD, 7x UARTs, 2x I2C, 1x CAN, 13x PWM outputs, 5V BEC
Loaded with an array of features and plenty of room for peripherals, the Matek H743-SLIM V4 is designed for demanding FPV, long-range, and autonomous builds. It’s compatible with INAV, Betaflight, and ArduPilot, and offers significantly more processing headroom than F4-based flight controllers.
Compared to the previous V3 version, the H743-SLIM V4 introduces several hardware upgrades while keeping the same board layout and pinout. The 5V BEC output has been increased from 2A to 2.5A, the filtered 5V / VBAT output has been increased from 1A to 2A, TVS protection has been added to the main battery input, and additional MCU I/O protection has been implemented. The barometer has also been upgraded from the DPS310 to the more environmentally resistant DPS368.
Alongside its ultra-fast H7 480MHz processor, the specification includes dual ICM42688P IMUs for clean and stable gyro data, a built-in AT7456E OSD, 13 PWM outputs, 7 UARTs with inversion, 2x I2C, 1x CAN, switchable dual camera inputs, and a MicroSD card slot for Blackbox logging. DJI FPV OSD is supported via any spare UART.
Current version is V4.
