Pixhawk Mini Overview

Under construction. Requires connection diagrams and more images of ports

The 3DR Pixhawk Mini autopilot is a next-generation evolution of the Pixhawk (designed by 3DR in collaboration with HobbyKing). It is about 1/3rd the size of the original Pixhawk and has more powerful processors and sensors.

The Pixhawk Mini is based on the PX4 open-hardware project and has been optimized for the PX4 flight stack.

Product comparisons

Pixhawk Mini vs Pixhawk (original)

  • One-third the size - from 50x81.5x15.5mm to 38x43x12mm.
  • Rev 3 processor for full utilization of 2MB flash memory.
  • Improved sensors, both primary and secondary IMU MPU9250 and ICM20608 respectively. The result is more stable, more reliable flight and navigation.
  • GPS+Compass module included. Features the Neo M8N with GLONASS support; compass HMC5983. Expect faster and stronger GPS lock.
  • Micro JST connectors instead of DF-13. These are much easier to work with.
  • Integrated piezo speaker and safety switch.
  • Natively supports 4S batteries with the included PDB.

Pixhawk Mini vs Pixfalcon

  • Improved sensors, both primary and secondary IMU MPU9250 and ICM20608 respectively. Expect better vibration handling and reliability.
  • CAN interface for UAVCAN support.
  • Includes 8-channel breakout servo rail for planes and other vehicles requiring powered PWM output.
  • Includes I2C breakout board for a total of 5 I2C connections.
  • Similar size.

Pixhawk Mini features an advanced processor and sensor technology from ST Microelectronics® and a NuttX real-time operating system, delivering excellent performance, flexibility, and reliability for controlling any autonomous vehicle.
