WARAN pico

The Ubiquiti Picostation Ubiquiti is a lightweight Linux device, running openwrt(backfire 10.03). The serial port(TTL levels) is only on the printed circuit board, so it's useful for digitzers with ethernet output like the RT130. It can be powered over the ethernet port. So the picostation gets the power direct from the Reftek, on the NET Connector Pin N,M. The Port can draw 1,1A at 12V.
