Introducing the AUAV X2.1 Flight Controller


The AUAV X2.1 is all about lessons learned. The X2 was a very successful board but there was still room for improvement. Following the PixRacer project we had time to invest into making the X2 the high quality PixHawk replacement we intended it to be. Major changes include: updated IMU sensors, power supply has been redesigned, headers have been laid out more logically, remote USB connector, industry standard 30.5mm mounting points.

Questions and comments are welcome!

  • Hi Jordi,

    Sorry but I'm confuse in version. I'm thinking that x2 was replaced by pixracer. So what is the difference and which version to choose ?

  • Developer

    For those waiting since September 2016 (=P).  mRo has the X2.1 available now:

    mRo X2.1 Rev 2
    The mRo X2.1 Rev. 2 is the reduced version of PixHawk1 with better sensors and more flexibility. This board will 'work out of the box' with PX4 and A…
  • I waited this for a long time and ask many times but I hope that fails because any response and no news for a long time, It's a pitty, looks cool design for little builds; I bought a MROBOTICS authorized pixracer at the end, nice support.

  • @Kocmoud I was looking forward to order one of those... any Indication when you will be able to deliver?

  • Any new news about this board?

  • I am a guy who waited for X2.1 but after you could not solve the issues, I dumped you for the Pixhawk 2.1.

  • Johnathan - Who are you and what are you talking about?
  • They failed to deliver the product again!

    No more trust in AUAV!

  • Hi Phil, cannot buy the thing. It says undergoing beta testing. any update?

  • It will be great if you could produce the case for it as Pixracer in the meantime.
