MicoAir NxtPX4v2 Flight Controller
Description:
MicoAir NxtPX4v2 Flight Controller is a compact, high-performance flight controller developed from the HKUST Aerial Robotics / Nxt hardware family. It features an STM32H743 MCU, dual BMI088 IMUs, an SPL06 barometer, and microSD storage, along with 7 UARTs, 8 PWM outputs, external I²C and SPI buses, and independent 5 V / 12 V BECs. The flight controller supports both ArduPilot and PX4 and is well suited to UAV projects that require substantial processing performance, redundant IMU sensing, and open hardware resources.

Hardware Specifications
Processor and Sensors
The STM32H743VIH6 provides a 480 MHz clock speed and 2 MB of Flash. Two BMI088 IMUs provide independent inertial measurements for sensor-consistency checks and redundancy. The SPL06 provides barometric altitude measurements.
NxtPX4v2 does not include an onboard magnetometer. When heading information is required, connect a GPS module with an integrated magnetometer or a standalone magnetometer through the external I²C bus.
Interfaces and Outputs
- 7 UARTs for GPS, telemetry, digital video, receivers, ESC telemetry, and other devices.
- 8 PWM outputs, each usable for a motor or servo.
- 1 external I²C bus for magnetometers, airspeed sensors, and other devices.
- 1 external SPI bus for advanced expansion.
- 3 AUX GPIOs for custom functions.
- 2 ADC channels for voltage and current sensing.
- microSD for flight-log storage.
- SWD for low-level debugging and recovery.
Power and Mechanical Specifications
The flight controller provides regulated 5 V / 2.5 A and 12 V / 2.5 A outputs. The power input supports 3–6S batteries.
Dimensions and Installation
Installation recommendations:
- Use 20 × 20 mm soft-rubber standoffs or another vibration-isolated mounting structure.
- Install the board according to its arrow. If the board is rotated, configure the correct orientation in the firmware.
- Keep GPS antennas, power cables, and digital video-transmitter antennas away from the IMU area.
- Leave enough service clearance for the USB Type-C connector and microSD card slot.
- Dual IMUs improve diagnostic capability but do not replace proper mechanical vibration isolation.
Interface Definitions
Typical Wiring:
Wiring principles:
- Connect a peripheral’s
TXto the flight controller’sRX, and itsRXto the flight controller’sTX. - Every serial peripheral must share a common ground with the flight controller.
- Connect the primary GPS to UART1 and an external magnetometer to the external I²C bus.
- Connect the DJI O3 to the dedicated UART3 interface, checking the 12 V pin and wire order before connection.
- Connect an SBUS or CRSF receiver to UART5.
