I'm creating layout for my PCB and I want to use Gvove connector in SMD package (http://www.seeedstudio.com/wiki/images/e/e0/3470120P1.pdf). But footprint from the datasheet doesnt have all the required dimensions. May be somebody knows the dimensions B,C,D ?
Amazing. How some engineers could indeed forget putting half of the critical dimensions here? How can Seeed publish this datasheet as if it was useful?
Anyway... I made some research. It appears this same connector is used on some dev kit of TI called "SimpleLink SensorTag Debugger DevPack" (dunno what it is exactly), which mentions Grove conectors in its marketing material. And the BOM lists the connector part number as 1125R-SMT-4P, which is the part number mentioned in the datasheet you linked and also given by Seeed on its Open Parts Library catalog. So I'm quite confident it is exactly the same.
So I downloaded the design files, loaded the gerber files in some gerber viewer tool, and measured the dimensions on their layout:
It gives: B=3.4mm, C=4mm, D=3.6mm.
Just noticed Hayman updated his answer. He doesn't obtain the same results, but most certainly, both layouts are appropriate. They just don't have the same clearances. Well, maybe you can buy these conectors, measure, and report back.
After doing some digging around I found the wiki page which has some eagle files for the boards.
From there I've managed to open the files and get the dimensions directly from their .brd files.
The sizes as determined from their eagle files.
B = 2.7mm
C = 4.6mm
D = 3.2mm
The board which I have taken the dimensions from is this board here this was the only one on the wiki with a right angle surface mount and eagle files that looked correct
Edit: After a little more digging around in the eagle files it seems that they call the footprint 'HW4-SMD-2.0-90D'
This matches up with the datasheet found here.
