Matek H7A3-SLIM Flight Controller - 2-8S STM32H7Enter the Matek H7A3 SLIM. Its thin, its fast, and its probably more capable than the pilot holding the transmitter. If you're building a long range cruiser or a racing rig that needs to cut through the air like a hot knife through butter (or a drone through a cloud), this is your huckleberry. Why You Want It Most flight controllers are built like they're expecting to survive a nuclear winter. The H7A3 SLIM is built for people who understand that

Enter the Matek H7A3-SLIM. It’s thin, it’s fast, and it’s probably more capable than the pilot holding the transmitter. If you're building a long-range cruiser or a racing rig that needs to cut through the air like a hot knife through butter (or a drone through a cloud), this is your huckleberry.

Why You Want It

Most flight controllers are built like they're expecting to survive a nuclear winter. The H7A3-SLIM is built for people who understand that weight is the enemy and processing power is the only god worth worshipping. With an STM32H7A3 processor, this board thinks faster than you can regret that last 'full-throttle' dive. It handles 2S to 8S LiPo power, because apparently, 6S just isn't enough to satisfy your thirst for speed and potential fire hazards.

Specs (For the Spreadsheet Nerds)

  • MCU: STM32H7A3RIT6, 280MHz (Fast enough to calculate your mistakes in real-time).
  • IMU: ICM42688P (SPI1) (Steady as a surgeon on espresso).
  • Baro: SPL06-001 (SPI2) (Knows exactly how high you are—altitude-wise).
  • OSD: AT7456E (Classic visuals for your goggles).
  • Blackbox: 128MB Flash (To record the exact millisecond you hit that tree).
  • UARTs: 6x Sets (Enough ports for your GPS, VTX, RX, and probably a coffee machine).
  • Input Voltage: 6~36V (2~8S LiPo) (Yes, 8S. Don't blame us for your charred ESCs).
  • BEC: 5V 2A & 9V 2A (Powering your gear without breaking a sweat).
  • Dimensions: Slim Profile (Because girth isn't everything).

In the Box

  • 1x Matek H7A3-SLIM Flight Controller
  • A bunch of vibration-damping gummies (To hide your shaky mid-air thumbs)
  • Connectors/Wires (The stuff you'll inevitably lose under your workbench)

Compatibility

This board speaks ArduPilot, Betaflight, and INAV fluently. It doesn't care about your software tribalism; it just wants to fly. Perfect for Long Range builds, Cinelifters, or your 'secret' project that's definitely not going to crash.

Highlights

  • STM32H7 Power: 280MHz of pure, unadulterated processing speed.
  • 8S Ready: For when you want to turn your drone into a low-earth orbit satellite.
  • Dual BEC: Dedicated 9V for your high-power VTX and 5V for everything else.
  • Slim Design: Fits into tight frames where other H7 boards fear to tread.

Notes

This is the SLIM version. If you were looking for the version that includes a built-in kitchen sink, you're in the wrong place. Ensure your soldering iron is actually hot before touching this board; cold joints are the leading cause of "it worked on the bench" syndrome.

Disclaimer

We are not responsible for your 8S-induced adrenaline overdoses or your inability to solder small pads. Fly responsibly, or at least film the crash.

Still Here?

If you're still reading, you're clearly an SEO crawler or someone who really appreciates a well-placed insult. Either way, stop stalling. Your long-range build isn't going to finish itself, and this Matek H7A3-SLIM is the only thing standing between you and FPV glory. Buy it, fly it, try not to break it.

Perfect solution
Size: 20FT, Color: White
Incredible value - solves our phone charging needs without bulky chargers attached to traditional extension cords… aesthetically superior with outlet cover and flat cord that we plan to conceal between tiles. A+

Great Extension Cord for hard to reach places.
Size: 5FT, Color: White
Wasn't sure if I would like this or not but I really do. We have the stand up version (not by same vendor) but really liking this smaller version that I was able to stand on edge and not take up valuable room on my side table. We used it for the outlet under the bed to the bedside table. Has enough power to run multiple items with no issues. I like that it comes with USB, C, 2 prong, 3 prong. I didn't use the included cover but that was because we had something else plugged into the other socket.

Decent

I needed a heat gun to make it a little more pliant to get the kinks out but otherwise I loved it
