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.

"Outstanding support and a seamless process!"
Great experience with Asurion insurance through Amazon. I wasn't sure how to register my items for the monthly plan, but the customer support team in the chat was incredibly efficient and guided me through the entire paperwork process smoothly. Furthermore, the service I received at the repair shop (Break Fix) was excellent. The whole process was seamless, and I received my digital gift card without any issues, which I’ve already applied to my Amazon account. I am very grateful for their professionalism and how easy they made everything. Highly recommended!"

Received giftcard money to replace my plan-protected malfunctioning motherboard
I've been subscribing to the Asurion protection plan for a while. Recently, an Asus Prime PC motherboard I had bought a few months ago on Amazon stopped working well. I ended up considering filing a claim with Asurion to see if they would either fix/replace it or issue the purchase price money, so I could buy the failed electronics replacement component again for my custom-built PC. I went to the protection plan's website and started the claim filing process but couldn't find the category my failed component would be under in order to select it from the drop-down list. I ended up messaging the live customer service. The chat messaging was somewhat slow, the agent told me they were experiencing some communication delays throughout their systems. Ultimately, the agent was very kind and understanding, and completed the claim filing process for me on her side by asking me to provide the necessary info such as the item's product name, date of purchase, price before taxes, etc. I received a printable UPS shipping label in the email, printed it, and returned the item in the mail. Approximately 2 days later, I received an Amazon giftcard code in the email with the dollar amount equal to the item's price before the sales tax. Then I redeemed the giftcard code on the Amazon page and proceeded to apply the giftcard money to my next purchase of a replacement Asus prime motherboard, and it all worked out successfully. Therefore, I had no issues with the protection plan service and recommend it to others.

Fast and easy but I dont trust the process to be fully automated.
The process was very smooth and fairly quick. The only challenge I had was that the CLAIM status showed complete but I had to manually go look up the status. There was no email or notification it was closed. After manually checking the status, I called customer support and they said since I called in, they would process the payout. I wonder if I didnt call in if they would have processed it? Also, the phone rep said they would issue me a amazon egift card but then the next day I received a email saying they mailed out the payout. Very poor communication but so far the process was easy and fast.

Excellent Warranty Coverage – Fast, Fair, and Hassle-Free
I purchased the ASURION 3-Year Portable Electronic Accident Protection Plan ($500–$599.99) for an Android 13 8.8” touchscreen stereo installed in my BMW (CCC system). After about two years of normal use, the Android stereo stopped working completely. I filed a claim through Asurion’s website, and the process was straightforward. Initially, Asurion asked me to remove the unit and prepare it for return, advising that they would email me a prepaid shipping label. I de-installed the stereo from my car and packed it up as instructed. After two days passed without receiving the shipping label, I was about to follow up—when I received an email notifying me that Asurion had issued a full refund of $459.00. I did not have to ship the unit back. That level of service exceeded my expectations. The claim was handled quickly, communication was clear, and the resolution was fair and hassle-free. I purchase an Asurion protection plan with every high-dollar item I buy on Amazon. I’ve had to file a three claims over the years, and each time the experience has reinforced that this coverage is well worth the cost. When something fails outside the manufacturer’s warranty, it’s a relief knowing Asurion stands behind the product. Highly recommended for expensive electronics.

PROTECTION WITH ABSOLUTE EMPATHY & RESPECT
Had an issue with a product I purchased over a year ago along with an Asurion protection plan. Thank God I chose this extended plan. I was waiting for a return ticket you get it repaired and Asurion sent me a full refund. I am so grateful for Asurion and I encourage everyone to get these plans and get the added protection on products NOT made as they once were. We as buyers are terribly taken advantage of with the garbage sent to us that we pay very very high costs of. Asurion has NEVER failed me and the customer service reps are extraordinary and kind and very very respectful. Thank you to you all at Asurion, Johnny A. Cheers...
