Introducing Pixhawk2.1, the worlds most advanced autopilot for open autonomous unmanned vehicles. Easy to use, redundant, temperature controlled and vibration isolated.

Key design points

  • Easy to use.
  • All-in-one design with integrated FMU and IO.
  • Separate power supplies for FMU and IO (see power architecture section).
  • On-board battery backup for FMU and IO SRAM / RTC.
  • Sufficient I/O for most applications without expansion.
  • Improved sensor performance.
  • Improved microcontroller resources.
  • Increased reliability and reduced integration complexity.


  • Pixhawk2 Autopilot (Cube and Carrier Board)
  • Power Supply Module (PSM)
  • Pixhawk 2 Cable Set
