Matek H743-Mini V3 Flight Controller

The Matek H743-Mini V3 is a compact 20x20 flight controller built around the STM32H743 processor, giving mini and tight-stack builds H7-class processing headroom. It runs Betaflight, ArduPilot and INAV, making it a flexible pick whichever firmware your build standardises on.

Key features

• STM32H743 MCU (480MHz, 1MB RAM, 2MB flash) with dual gyros (ICM42688P and ICM42605) for accurate, low-noise flight data.
• Integrated DPS310 barometer and AT7456E OSD chip on board.
• MicroSD blackbox logging, several UARTs for receiver, GPS, telemetry and VTX control, plus a CAN bus for DroneCAN peripherals.
• Dual camera-input switch simplifies wiring analogue and digital video setups on the same board.
• 20x20mm mount with silicone and brass grommets included for vibration isolation.

Rated for 2S-8S LiPo input with onboard 5V and 8V BECs, it suits mini freestyle quads and tighter long-range stacks that need full H7 performance in a 20x20 footprint.
