I want to put my Omega 2 on a circuit board, so what is the distance between 2 Pins ? I ordered a circuit board with 2,54 mm but this is not the correct size. In the pdf documentation I found something with "Pitch Type" 2.0 does it mean 2.0 mm distance between the Pins ?

Best Regards from Germany

Now I have to find a solution, using a lets call it "non standard 2.0 mm" circuit board or using an adapter like this

or this

Or is there a small official adapter/holder for a 2.54 mm pitch available ?

In the case of Omega2, it's 2mm pitch.

If you search the forum, you'll find several solutions such as buying the 2mm pin socket from fleabay.

IMHO, if you only need to access few pins just for your own project need and if it's a permanent setup (i.e., not unplug and re-plug repeatedly), you can get away by using improvised solution such as wire-wrap IC (long leads) bent pins.

ccs_hello

The Mini Dock is an official adapter/holder (and more...)

Its a little bit difficult to search or to explain in an other language if you dont know the "official wording" so sorry for that. The german word is "Lochrasterabstand" (maybe helpful for other germany using google)

thx 4 the link

The Mini Dock is no solution for my project because I need the LAN and GPIO pins.
For playing around I already have the Expansion Dock

finally thx to all
