KiCad has separate libraries for schematic and PCB. This allows for shared symbols and separately shared footprints. A couple examples:
- One USB connector symbol in the schematic but then you can choose different footprints based on: inline, horizontal, vertical, THT, SMT, and different manufacturers who all have different ways of the shield connecting to the PCB.
- One 14-pin DIP footprint for the PCB that can be referenced by lots of different schematic symbols (to cover the large collection of 7400 series logic chips).
I see Rene replying so he is probably pulling up the FAQ links that I’m about to pull up…
EDIT: Yep. He did. One more link to help you as a supplement (and errata to) the included documentation is the FAQ button in the upper right-hand corner of this forum. (Unless you have enabled the dark mode theme for this forum where that link is missing.) This is the forum’s master index of FAQ entries:
