Floppy connector un-f*ck pcb

Post by exxos » Mon Oct 08, 2018 1:14 pm

Thanks to Icky for unravelling this connector chaos..I have started in a new un-f*ck PCB... Highlighted below are just the GND connections to illustrate the changes which matched the image provided by Icky.

I have checked all the other pins and all seemed to be swapped out correctly...

What seems to have happened is my connector pinout was actually correct..

But electrically what I had labelled as pin one for example, was actually pin three electrically in the schematic. :roll:

Problem being while I labelled up the correct pins in the PCB part, and the correct pins in the schematic part and labelled up correctly, there was a third connection for electrically connecting the pins between schematic and PCB part,which I must have forgot to do (again) :( I really wish there was a better editor in Eagle. One where everything is just on one screen rather than flicking around all sorts of screens and boxes to make all the connections :roll:

As before, I will post the PCB file here (Hopefully later today) so anyone who wants to order them can do so.

I would suggest people order from OSH ($8.20 for 3 boards) Particularly people USA direction (or outside of EU). Of course anyone in the world can order these, it will be a lot quicker and cheaper than waiting for boards to arrive to me and then having to ship them out.
