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!

Comments
Dario Salas,
We are using the same as PixHawk1 (micro F100):
https://github.com/PX4/Firmware/blob/master/src/drivers/px4io/px4io...
Johnatan,
As PixHawk1, PixRacer and other autopilots they don't provide power on the servo rails. Is not recommended due to variations in power requirements among all platforms. UBEC or power coming from the ESC is recommended to power your servos or actuators.
Dario Salas, I will get back to you on that one.
Are the servo pins powered on this board, so we can attach the servo leads directly to the X2.1 or like Pixracer we have to use a UBEC to power the servos?
@Marc thanks for the help!
IMPORTANT: The pin out above has changed slightly. On X2.1 Rev 2 we remove Telem2 JST-GH connector on the side and replaced it with the GPS port, so is more convenient. So the serial ports have been rearranged. We will release a visual datasheet shortly.
COOllll, keep Us update with test and experiences; in wishlist for next build ;) looks nice choice for little space builds.
Ok thank you Mark. Yes should be good, especially for difference between platform ...
The X2.1 has a lot more I/O options. It is pin compatible with a Pixhawk 1. For example Pixracer has only 6PWM outputs. It is for more 'serious' DIY applications.
Maybe Jordi can start a brand new thread with a better breakdown and comparison.
Sorry want to lear more about it
Pixracer and x2.1 and different platforms. Pixracer doesn't have the IO chip and therefore way less inputs and output pins.
