Ah, so the spacing should actually be 1 inch rather than 1.1?
yes 0.998 to 1.0 isn’t going to matter, 0.998 to 1.1 would be a bigger issue.
There aren’t many guidelines and “it works for me” is as good a criteria as any :-), I (and some other people) find a schematic that doesn’t match the bb / pcb views annoying (the Raspberry PIs are one such). Neither is right or wrong as both will work, it is just personal preference.
I’ll have to look again, but there are two buses, one with non existent pins (which won’t do anything) and the other I think connects two pins that are not ground, but I may have read it wrong.
That would be useful. as would height / width of the actual board (I couldn’t even find measurements on any of the sites selling that board that I found).
Unfortunately web site maintance along with development has pretty much died. Signup to the forums has been dead for months for instance, so we aren’t getting any new folks in here. I’m trying to get to the point of getting development at least possible, but it looks like interest in Fritzing has pretty much died. I’ll fix up your part a bit (make breadboard work, fix up the buses etc) and post what I would do to make this part. I’ll guess at the position of the mounting holes til we get measurements.
