The Vin input is not connected to anything. The Arch Pro is designed to be powered from 5V.

If you wish to verify this, grab the schematic from the SeeedStudio Arch Pro wiki page: http://www.seeedstudio.com/wiki/File:Arch_Pro_V1.0_Schematic.pdf

Thanks for your answer, Do you know if I can power the board with 7,5V battery on the 5V pin.

Applying 7.5V to the 5V pin is not a good idea. It will likely damage any shields plugged into the board. Also the on-board 3.3V regulator may overheat (due to the increased voltage drop).

I suggest you use an external 5V regulator, or a battery pack with a built in regulator such as those sold as mobile phone emergency chargers.
