I pulled it out the other day I was bored. I went to use it and found the Pi was disconnected from the MK1 hub . small Square board. there are 4 wires going over to the PI one on a single wire and the other three wires to one connector.
I can't find my docs to figure out where they go. I only figured out the power connection and it does work. I guess I dont need those other 4 wires :D
