First up, sorry if this a noob question!
I'm just in the process of building my very first Circuit Sword Lite build and was wondering how a PSP 1000 stick connects to the board? I see the six pads labelled up, down, left, right, gnd and 3.3v, but the stick only has four outputs for gnd, power, up/down and left/right.

How do the shared X/Y outputs from the stick connect to the separate X/Y inputs on the board?

Or, is there a better stick to use with the CSL?
Hope this makes sense and thank you in advance!
