MicoAir H743 + 50A is a flight controller stack suitable for 5" freestyle drones up to 7" long-range drones powered by 3–6S Lipo batteries. The stack is especially designed for builds requiring advanced stabilization or autonomous flight capabilities. MicoAir H743 supports ArduPilot firmware (default), as well as PX4, Betaflight, and iNav. Thanks to its rich feature set, it supports a wide range of sensors, servos, and other peripherals. The board features an SD card slot for storing logs, missions, or terrain elevation maps.
At the core of the controller is a powerful STM32H743 processor, dual BMI088 and BMI270 gyros, a DPS310 barometer, and an IST8310 magnetometer (external magnetometer is also recommended). The board includes 7 UARTs, I2C and CAN buses for connecting peripherals. It provides 10 PWM outputs for motors, servos, switches, or other accessories. The board also features a USB-C connector, an OSD chip for analog video, and 5V/3A and 9V/3A BECs.
The stack is complemented by 50A ESCs running Bluejay firmware. The ESCs are equipped with a current sensor and a TVS diode for protection against voltage spikes.
The board does not have a dedicated output for buzzer or LED strip (Betaflight/iNav). With ArduPilot and PX4 firmware, external LEDs can be used.
