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!

They failed to deliver the product again!

No more trust in AUAV!

Johnathan - Who are you and what are you talking about?

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.

Any new news about this board?

Comment by Andreas on June 5, 2017 at 12:39pm

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

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.

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

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 ?

Comment by Jordi Muñoz on August 30, 2017 at 8:05am
@kiki boy

Pixracer and x2.1 and different platforms. Pixracer doesn't have the IO chip and therefore way less inputs and output pins.

Are different platform *
