MicoAir743V2 AIO – H743 Flight Controller & 45A BLHeli_32 ESC

MicoAir743V2 AIO – H743 Flight Controller & 45A BLHeli_32 ESC

H7 Performance in an AIO Form Factor The MicoAir743V2 AIO is a standout in the micro-class category. While most AIO boards rely on F4 or F7 processors, MicoAir has integrated the STM32H743VIT6, providing a massive 480MHz clock speed. This allows you to run high-frequency PID loops and complex bidirectional DShot configurations with plenty of CPU overhead to spare for GPS navigation and advanced telemetry.

The integrated 45A 4-in-1 ESC is powered by BLHeli_32 firmware, supporting up to 6S LiPo input. This makes it robust enough for aggressive 3.5-inch freestyle or lightweight 5-inch racing builds. With built-in Blackbox logging, multiple UARTs, and an ICM42688P gyro, it delivers the “locked-in” flight feel of a full-sized stack in a fraction of the weight and volume.

Key Features

• Ultra-Fast H7 Processor: STM32H743 running at 480MHz for ultimate stability and feature support.

• 45A BLHeli_32 ESC: High-current capability for 3S-6S power systems with bidirectional DShot support.

• Vibration-Resistant Gyro: Features the ICM42688P for clean, low-noise signal processing.

• Rich Connectivity: Includes 7 UARTs, I2C, and dedicated pads for digital VTX (DJI/Walksnail) and analog systems.

• Compact AIO Design: Combines FC and ESC onto a single board, perfect for tight frame builds.

• Onboard Blackbox: Integrated flash memory for detailed flight data analysis and PID tuning.
