Enter 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 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 arealtitude-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: Dedica
