Another good thing I found about the UAVP. Currently the board can handle 3 Gyros, one 3 axis accelerometer, one magnetic sensor (compass) and one GPS Module At the same time. You can also add one barometric Pressure sensor or a parachute trigger but I'm no sure if it will work in conjunction with the other sensors or you have to disable one of them.

For now you can see the assembly manual (PDF format) and schematics (Inside the manual) of the main board at:

It is in German. Copy and paste into word and use the translation tool. It seems that this machine is the Swiss knife of the quadrocopters.
