Matek H743-Slim V4 Flight Controller

Matek H743-Slim V4 is a 30.5×30.5 flight controller for FPV builds that need an H743 processor, a dual ICM42688P gyro and support for Betaflight, ArduPilot or INAV. It suits stack-based builds where clean wiring matters, with USB-C, onboard logging, a barometer and enough I/O for GPS, camera switching and other peripherals.

Key features

• STM32H743 processor (480MHz) for demanding FC workloads and feature-rich firmware setups
• Dual ICM42688P gyro and an onboard DPS368 barometer for current-generation sensor performance
• Onboard microSD slot for flight logging and tune analysis
• 7 UARTs, 2 I2C buses, CAN and an SPI3 breakout for receivers, GPS units, telemetry and external modules
• Switchable dual camera inputs and switchable 5V/Vbat filtered outputs simplify camera and analogue-VTX wiring
• 2-8S input with TVS protection, filtered VBAT and regulated power rails for wider pack compatibility
