Also, here is the dimensional drawing of the outline for my breakout board:
it seems to fit well with the plug-in frames that I have.
Hi Andy,
Thanks for your quick answer, I think you're absolutely correct at 3.9 inches.
I've double checked the datasheet edge connector (made by EDAC) I'm using for my extender project.
And the "D" size for 38 pins (76 pins double sided) is 3.9 inches.
I didn't pay that much attention to that and used 3.8 inches for my project, whereas the exact information was right in front of me.
I also work in metric, I live in Europe (France) after all. But for electronics, I always try to make it imperial compatible, hence my board is 96.52mm (it should have been 99.06mm).
If you have some time to spare, there's a funny video by an english guy about metric vs imperial:
Best regards,
