Here are the list of TP spots on the PS3 controllers, the most useful ones anyway, for anyone that would want to make up an Arcade Stick, add an extra button or something similar.
Of the 15 versions of these controllers, that I know of, there are (so far anyway) 6 different TP layouts for them. These are a general pic of the different layouts, what controller version they're on and what they do.
NOTE: All of the TP spots are NOT shown in these pics, this is just for reference so you can tell which controller you have at a glance and what TP spots are what on that version of controller.These are for the USB Connector and they are the same on all versions of board.
TP1 - 5v
TP2 - D-
TP3 - D+
TP4 - Ground
This is for the older Six-Axis controllers.
Any of the
MSUPP 4.0 versions that have the 3 legged POTs. The TP spots may or may not be tinned with solder also.
