Matek H743-Slim V3 Flight Controller

The MATEKSYS H743-Slim V3 is a 30.5×30.5 mm flight controller built on the 480 MHz STM32H743 processor. It targets ArduPilot and INAV on multirotors, fixed-wings and VTOLs, and also runs Betaflight, bringing the logging and sensor redundancy that autonomous and long-range aircraft call for.

Key features

• Dual IMU (ICM42688P and ICM42605) on separate SPI buses for sensor redundancy
• DPS310 barometer and AT7456E analog OSD on board; DJI OSD works on any spare UART
• 7 UARTs with built-in inversion, 13 PWM outputs, 2 I2C buses and a CAN port on a JST-GH 4-pin connector
• MicroSD card slot for blackbox and flight logs
• Runs from 2–8S (6–36 V) with a 5 V 2 A BEC for the receiver, GPS and peripherals
• Dual camera input switch and a switchable 5V/Vbat filtered output

Wire a power module or your ESC's current output to the Current pad for battery monitoring, and power high-draw servos from a separate BEC, since the onboard 5 V regulator is rated at 2 A continuous.
