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.

You can get a 6 month Altium viewer license here, if you want to view altium designer 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.

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)

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.
