I’m sure that I’m missing something terribly obvious here, but I’m hoping folks here can help a noob out. I am working on a design that will be using a 9V battery connected to a board via a PJ-201A Barrel connector. There wasn’t a footprint for this in KiCad, so I found one that fits, but I think I may have a problem (footprint image below for reference).
According to the schematic and some other comments I found online, pin 2 (side) is a shunt and not connected to pin 3 (center/inside) when the plug is inserted. Does this mean that 2 and 3 should not both be marked as ground, as in the footprint, or is it irrelevant as long as I create a net between them on the PCB? I’ve not worked with this type of connector before and I’m a bit confused because I’m not getting a consistent voltage reading from my DMM when this is connected to a battery, and nothing is happening on the board.
I’m willing to admit that my problem lies elsewhere on the board, but I figured I’d start at the source and go from there. If this is working, as designed, I’ll keep debugging…
