What the main difference between the three MiniIpacs, from what I can see there is 1 - Board only, 2 - Board and Harness, 3 - Board, Harness, and USB Cable.
If I am right then the one with the USB Cable is 23 bucks more the the one with the harness and board... I have USB Cables, but want to make sure that this is right because it doesnt make any since.
