UMT H743-SLIM V4: an alternative to the Matek H743-SLIM V4

Looking for a Matek H743-SLIM V4 flight controller now that Matek has discontinued it? The UMT H743-SLIM V4 is our independently manufactured alternative, with the same core hardware specification and intended flight-control performance. Its STM32H743 processor, dual ICM42688P IMUs and 30.5 x 30.5mm mounting suit builds that need H7 processing and plenty of peripheral connections, rather than another evening rationing UARTs.

This is not a genuine Matek product. It is made independently at a different factory and is not manufactured, endorsed or officially supported by Matek. Matek branding and factory support are not included; buy this as the UMT version, not as an official Matek replacement.

Why You Want It

Because you’re tired of running out of UARTs and you’ve finally accepted that blackbox logging is the only way to prove that crash wasn’t your fault. This board is an absolute powerhouse, designed for builders who want everything. Dual IMUs for rock-solid stability, seven UARTs for all your gadgets, a CAN bus for next-gen peripherals, and enough PWM outputs to control a small army of servos. This is the “buy once, cry once” upgrade that ensures you won’t need another FC for a very, very long time. We’re here to help you part with your money wisely.

Features and Highlights

• Beefy H743 MCU: At 480MHz, it handles complex ArduPilot missions or high-RPM Betaflight filtering without breaking a sweat.
• Dual ICM42688P IMUs: Less noise, cleaner data, and a backup plan for when you decide to fly through a flock of pigeons. It’s premium, darling.
• Upgraded Power Delivery: The V4 boasts a beefier 5V BEC (2.5A) and 2A filtered Vbat output, giving your VTX and camera the clean, stable power they crave.
• Water-Resistant Baro: Features a new DPS368 barometer that’s environmentally sealed. It’ll probably survive a light British drizzle better than you will.
• Insane Connectivity: With 7 UARTs, 2x I2C, and a CAN port, you can stop choosing between your GPS and your camera control. Just plug it all in.
