Multiple components in a single file for reuse

Schematic
1

I am not sure I am asking this right. Being a software guy mostly I am trying perhaps force hardware into the same idea :slight_smile:

I am making a few boards with a few minor different variations. All of the boards contain a few “sub systems” that are exactly the same. IE: power schematic is the same on all. Vs. maintain 3 different schematics for all variation designs. I would like to be able to create this power schematic. Then just reuse that in all designs. Sort of import or link them. This way I could update the “master” if needed and then pull in changes to all over schematics. Is this something kicad can do?

thanks!

As far as I know you can’t do this with Kicad. It basically one schematic/PCB per project. If you need to have variations then you will need to have a seperate project for each. They will also not be linked.

@ril3y There’s a feature request for this, if I get you right

If your are talking about schematic only without having pre-routed bits for the PCB, then you could use hierarchical sheets for that. In the power part example, your sheet will have two inputs (VIN, GND_IN) and two outputs (VOUT, GND_OUT) and all components for this power part will be inside of the sheet.

Now you only need to use the same sheet for all the designs that require it.

Note that the cross-project use of hierarchical sheets will die (or be deprecated) as soon as #2263 yields something sensible.
