I'm trying to understand this mechanical drawing so I can create a layout for it in gEDA PCB.
Specifically on page 4. I've already managed to place GND 1 and GND 2; those were fairly simple to work out. But GND 3 confuses me, because it's apparent from close inspection of the drawing that it doesn't quite line up with GND 1 and the offset doesn't appear to be given. The same is true for GND 4 which doesn't quite line up.
Also on a semi-related note it is unclear whether the pins are in the order as they are on the SD card or if they are numbered arbitrarily - that is, does pin 1 correspond to pin 1 on the SD card?
While this isn't strictly electronics, I think it passes as an appropriate question because it is an electronic connector and it requires a PCB layout.
