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!

Hello Luc, 

The MRC0253 will be available soon, is very new and we haven't been able to add it to the store yet, but is available in the X2.1 kit. 

The I2C can be accessed through the GPS connector (as standard). We have cables that split the I2C signal out from the GPS, the MRC0218. Also, our GPS offers an auxiliary i2C output for convenience, you also check our GPS/i2c splitter or our Active i2c HUB. So you have plenty of options to play with. =) 

All the kits include the JST-GH to USB converter, which is always needed, so you should be covered. 

You can check our manual here

Warmly,

Thanks for the reply Jordi.

Mine has shipped yesterday , I'm curious to test it and compare the X2.1 to traditional Pixhawk .

Hope that Invensense sensors will make the difference.

More outputs in a smaller factor is an advantage over Pixracer.

I have receive yesterday  the board and was able to install Arduplane 3.8.2 with Mission Planner.

Parameter AHRS_ORIENTATION must set to 2 if you mount your board with front in front of the plane.

Do someone knows where I can find  a 3D file  for printing the case for the X2.1 V2 ?

Hello Luc Maximilien, 

Yes, the orientation for Ardupilot is moved 90 because of the bootloader configuration. We will post instructions on how to update it (But after Mission Planner is updated). Future shipped boards will include this new update. 

Right now I'm working on this case for X2.1, is my first 3D Cad design so don't expect much:

This case will allow you to populate pins on right angle or upward configuration. Also, is 3D printer friendly.

Hi,
I would like to buy an light and high quality autopilot with more than 6 PWM outputs to run Arducopter on it.

The mRo x2.1 Rev 2 seems to me the most interesting option currently. But I can only find 3 topics about the autopilot in the forum.
And now I’m wondering why? Is it a bad idea to buy that autopilot because it is rare and will lack support soon?
Has anyone experience ordering at mRo from Germany?
Thx,
Tobias

I have one of those. After initial Confusion with IMU Orientation it is working as it should :-)

Shipment was fast even with the non recommended Shipping option. Quality is flawless.

Hi,

I ordered 2 of them because I have read that there are aux channels and that it is like a PixHawk. No I read on Github that the aux channels need custom code? Is that true?

Hello Tobias, 

I'm trying to recall here. The X2.1 exposes the same pins as PixHawk1, if a remember correctly, some of those pins might need custom code due to a bug or a software issue that is affecting all hardware based on PixHawk1, this includes x2.1. 

Comment by Tobias on May 11, 2018 at 8:26pm

Hi Jordi,

thank you for the answer. If I understand it correctly, I will not need coding to trigger my camera from CH1-Ch6? I hope so! My parcel is held in custom since more one week, I'm hope they will process it some day ...

Are there any online store to order x2.1 in Europe?
