MicoAir743 V2 AIO 45A Flight Controller

The MicoAir743 V2 AIO is a high-processing all-in-one board designed for advanced micro drones, long-range explorers, and compact autonomous builds. By pairing a top-tier STM32H743 microcontroller with a robust 45A AM32 ESC on a single PCB, this flight controller brings full-scale computational power to the popular whoop-style form factor.

Key features

• High-speed STM32H743 MCU easily manages complex ArduPilot navigation and intensive INAV filtering workloads.

• Integrated AM32 4-in-1 ESC delivers a smooth, linear throttle response and handles continuous 45A loads.

• Direct compatibility with 3S to 6S LiPo batteries allows for versatile powertrain setups.

• Comprehensive I/O layout with native hardware UARTs and I2C support for integrating GPS modules, compasses, and digital HD VTX systems.
