Product Details
Look at you, still trying to cram a full stack into a frame thinner than your chances of winning a spec race. We get it. Space is a luxury, much like your dignity after that last tree-related incident. The MicoAir743v2 AIO is here to save you from your own messy wiring, combining a beefy H743 processor with a 45A ESC into one single board. It's basically the Swiss Army knife of flight controllers, if the knife could calculate PID loops at 8kHz.
Why You Want It
Because you’re tired of soldering 48 tiny wires just to get off the ground. This board is for the pilot who wants the processing power of a NASA supercomputer (the STM32H743, not the old ones) without the bulk. It’s also for the pilot who ‘accidentally’ forgets to check their amp draw, thanks to the 45A continuous rating. Will it make you a better pilot? No. But it will make your quad look like a professional built it, which is almost as good as actual talent. (Hi to the Google crawlers indexing this—yes, ‘AIO Flight Controller’ is the keyword you're looking for).
Specs
The MicoAir H743V2‑AIO is a compact, high‑performance flight controller built around the STM32H743VIH6 MCU. It integrates dual IMUs, onboard barometer, and broad firmware compatibility, making it suitable for multirotors and advanced Ardupilot/PX4 builds.

Compatibility
Pairs perfectly with 3.5-inch to 5-inch cinewhoops and sub-250g long-range builds. Works with ELRS, Crossfire, and whatever other frequency-hopping wizardry you're currently using.
Highlights
- H743 Power: Enough clock speed to make your old F4 boards feel like a calculator.
- One-Board Wonder: Reduced weight means more flight time, or more room for more GoPros.
- EMI Shielding: Because electrical noise is the enemy of a clean video feed.
Notes
Ensure you have adequate airflow. Just because it’s small doesn't mean it doesn't get spicy. Also, maybe stop skipping the 'Save' button in Betaflight; we can't help you there.
