The wallet firmware will configure the scanner for you on the first run, so no manual preconfiguration is required.
Here is how you connect the scanner to the board:
For convenience you can buy an Arduino Protype shield and solder & mount everything on it (i.e. this one)
On the top side of the board there is a jumper that defines where it will take power. You can change position of the jumper and select power source to be one of the USB ports or VIN pin and connect external battery there (should be 5V).
