MicoAir H743 V2 Flight Controller

The MicoAir H743 V2 is a 30.5x30.5 mm flight controller built around an STM32H743 processor. It suits 7-10 inch long-range quads and autonomous builds on 2-6S LiPo. It ships with ArduPilot and also runs PX4, Betaflight and INAV, so one board covers waypoint missions and manual freestyle setups alike.

Key features

• Dual IMU (BMI088 + BMI270), SPL06 barometer and QMC5883L compass on board.

• 8 UARTs and 11 PWM outputs for motors, servos, GPS, telemetry and other peripherals.

• Built-in Bluetooth telemetry on UART8 lets you connect wirelessly to a ground station or configurator.

• Separate 5V 3A and 12V 3A BECs: the 5V rail feeds the receiver, GPS and sensors, the 12V rail feeds the VTX and camera.

• DJI O3/O4 VTX connector plus an AT7456E OSD chip for analogue video.

• MicroSD slot for flight logs, missions and terrain data.

The onboard compass is close to the power wiring, so for reliable GPS flight modes in ArduPilot or PX4 add an external GPS with its own compass and mount it on a mast. PPM receivers are not supported; use SBUS, CRSF or another serial protocol.
