Matek H743-SLIM V4 Flight Controller
Let's be real, you're here because your F4 flight controller is starting to feel a bit... pedestrian. You've heard the whispers about H7 processors. Well, stop whispering. The Matek H743-SLIM V4 is the brains your high-performance drone has been begging for, with a 480MHz MCU that has more processing power than the toaster that runs our office Wi-Fi. If you're looking for a top-tier H7 flight controller in the UK, your search is over.
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.

A Word of Warning on the Matek H743-SLIM V4
This board is smarter than all of us combined. The included parts are as listed, but your ability to configure ArduPilot without consulting a 400-page wiki is not guaranteed.
What’s New on the H743-Slim-V4
- Higher Power Handling: BEC 5V output increased from 2A → 2.5A, and filtered VBAT current boosted from 1A → 2A.
- Improved Protection: Added TVS protection on input voltage and expanded protection across more MCU I/O lines.
- Upgraded Sensor: DPS310 replaced with the more robust DPS368, offering IPx8-rated resistance to water, dust, and humidity.
- Same Layout, More Power: All other functions, pins, and pads remain identical to the previous version for easy compatibility.
Still Here?
You've scrolled this far, you magnificent nerd. You've analysed every spec, you've mentally mapped out your wiring, and you're probably cross-referencing this with the official Matek documentation. You're our kind of people. This is arguably the best flight controller for a complex long-range FPV build or autonomous wing. Stop reading and start building. Go on, add it to the basket. With 7 UARTs and a CAN bus, this flight controller has more ports than a seaside town. Plug in all your gear without compromise. Upgrade your drone's brain and give your soldering iron a real workout.
