PC10004/PCA10005 connector pitch and spacing

[Gavin]

What is the pitch and spacing of the connectors on the underside of the PCA10004 and PCA10005 modules please? Is there a diagram showing dimensions anywhere in the documentation?

I don't have access to Altium and therefore can't open the design files

Look at the schematic (which is a PDF you should be able to open) and it tells you the exact connector, which is Samtec SFC-120-T2-L-D-MOD B, which google knows about; or you can open up the Bill Of Materials which also tells you the same thing and handily adds ..

1.27mm Pitch DIL Vertical SMT Socket Assembly, location pegs, double polarised, gold, 20+20-way

They're not the cheapest connectors in the world, if you get the actual Samtec ones, but there are some alternatives I've found in the past which are reasonable.

Many thanks - this is very helpful. Despite searching, I've been unable to find the schematic - do you have a link? (I need to know the spacing been there connectors too)
