Still need the connections (only to the Arduino pins or to pads as well? Am I correct the Arduino pins go to the screw terminals?) from the screw terminals to make a part. None of the pictures I have found have that kind of detail and it is needed to make a part. The physical layout should be obvious enough from an Arduino outline (and one of the jpeg images. )
edit
as an example this proto shield I recently did for someone has the connections that I am referring to (which I am assuming exist in your board, but are not documented anywhere I can find.)
Here they are implemented as traces between the arduino pins and the pads. I need a similar list for the board you have (which may be as simple as a straight on photo of both sides of the board showing how the traces connect between the screw terminals, the arduino pins and potentially the pads.)
