I looked at the Eagle files of the Arch-pro ( http://www.seeedstudio.com/wiki/Arch_Pro ...and there is a big surprise. The 3 pins GND and VIN are printed but NOT CONNECTED ! How is it possible to publish such a false documentation ! Thank you for your question...I was interested in a Arch_max. Robert
Robert, I own an Arch Pro and can assure you that the GND pins are connected. I think Seeed have used a copper flood to connect the GND net which is why it doesn't show when viewing the Eagle board file.
Shota, Is it essential that you use a 9V battery? I use a mobile phone portable charger to power my Arch Pro and shields. It takes 4 AA batteries and gives a regulated 5V output from a regular USB type A socket. I got it from Amazon for a few pounds. It works fine and does not get hot.
