Connecting to GPIOs on Tweener

I do this. I use wire-wrap wire (I think it's 32 AWG) and solder to the vias (through-holes) near the hirose connector on the tweener.



I chose the tweener because it's cheap to replace if I mess it up, and because it has a via for every single line that goes through the hirose 60 pin connector. I use the board layout (having downloaded Eagle) and the New 60pin connector chart to work out which via belongs to which signal.

If you want to do this, I suggest loading the PCB00028.brd file in Eagle. View > Display/hide layers... and Click "None" to turn off all the layers, and then turn on layers 1 (Top), 16 (Bottom), and 18 (Vias). Be careful to work out exactly which side of the board you're looking at, and exactly which is pin 1 etc. Use the fact that pins 28, 29, and 30 are all connected together - they're at the top left in the picture below.
