MicoAir H743 AIO 35A AM32 Flight Controller & ESC (25×25)

The MicoAir H743 AIO pairs a high-performance STM32H743 flight controller with a 32-bit AM32 ESC on a single whoop-style board. Designed for 3-6S builds, this AIO provides extensive processing headroom for complex ArduPilot, Betaflight, or INAV setups while delivering smooth, responsive motor control for demanding sub-250g and lightweight freestyle quads.

Key features

• STM32H743 MCU handles high loop times and advanced filtering with zero CPU bottlenecking.

• Integrated 35A ESC runs AM32 firmware for precise, configurable 32-bit motor management.

• Broad 3-6S LiPo input accommodates high-voltage micro builds.

• Standard 25.5x25.5mm mounting pattern integrates cleanly into toothpick and whoop frames.
