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

It's in the same hardware files package that the Altiums are in. Mine's called nrf51822 Development Kit Hardware Files 2.0, should be under the devkit downloads.

Under each sub-module (ie PCA10004) there's a 'Altium Designer Files' subdir, a 'Production Files' subdir which contains the BOM and a 'Schematic_Layout pdf files' subdir which contains the schematics.

None of that however helps with the spacing between the connectors, for that you do need to read the altiums, or work it out from the gerbers or guess from the pick and place file which, if I got it right (check this!!) puts them 1.1" apart .. which is an odd number. I just checked it with a crappy plastic ruler which seems to agree.

If you're doing what I was going to do, which is making a board using my old PCA10004, it ended up being cheaper to buy a Rigado module and mount that then buy the samtecs.

It is indeed. Apologies for slow response, but having looked in the Altium files with the free viewer, I can confirm that the connectors are 1.1inch apart - that is pin 1 on connector P1 is 1.1 inches away from pin 1 on connector 2.
