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.

Soft...but fluffy and tall
Color: White, Size: Standard (Pack of 2)
I've only had these pillows for about a week. They are a great quality pillow. The cover is soft and seems well made. My only complaint is that they are VERY full pillows. If you're tall with broader shoulders, you'll probably love them. If you're shorter with a smaller frame you will probably feel like your head is too high and your neck at a weird angle (my problem). There seemed to be mixed reviews about softness....I would consider these a nice medium pillow. Soft filling but firm enough that your head doesn't sink to the bed. Definitely NOT a down-like pillow, so if that's what you're looking for, this is not for you.

Soft, fluffy and surprisingly comfortable
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
I really liked these pillows. I tried to show different things in my photos because I wanted people to see the details: the design, how fluffy they are, and how full and thick they actually look. They are so full that the pillowcase even looks tight once you put it on, which I actually loved because they look luxurious and well-filled. At first glance they look very thick and high, but once you lay down they feel soft and fluffy instead of hard. They adjust comfortably and feel very cozy whether you’re sleeping, relaxing, or even reading before bed. I think they offer a really good balance because they feel supportive without being stiff. Of course, pillow preference is very personal—some people like lower pillows and others like higher ones—but for someone who likes fuller pillows that are still soft and comfortable, these are great. They are spacious, cozy, and feel like a very good purchase overall. I honestly don’t have any complaints so far. Definitely happy with them.

Great quality pillows. Very difficult wrapping.
Color: White, Size: King (Pack of 2)
The Pillows are the real deal. Very fluffy but with good support. I was surprised by the weight of the box they came in, pretty heavy so you know there’s good quality pillows inside. The one negative is that the pillows are packed in very very tight plastic because they come compressed. But the thing is, it’s really a chore to open them. You have to be careful not to cut through the plastic to the material, but the plastic is put on so incredibly tight that it’s even hard to get your finger underneath. But I found a way to open them. Near the top, insert A very flat metal ruler as far in as you could get it. Then cut through the plastic that’s above the metal ruler. That prevents a sharp tool from damaging the pillows. As you get through the plastic above the ruler, keep pushing the ruler further down into the package. Believe me, this simplifies what could be a very difficult unpacking. I am very surprised that the company that makes them does not insert the type of opener that you find on boxes you receive in the mail or even packages that you get from the grocery store where you just pull a tab and that opens the package. These are really good pillows, but you must be very careful about using a sharp object when opening the box and when trying to cut through the plastic. I am a strong man and have the tools needed, a very flat metal ruler, and a box cutter, knife, or razor. Good luck. !!

Comfy, supportive pillow.
Color: White, Size: Queen (Pack of 2)
The 2 queen sized pillows fluffed right out of the package. Very soft to the touch like laying your head in a marshmallow, nice support, and so comfortable. My neck did not hurt and I rested good. I usually use a My Pillow but these are just as nice.
