2 schematics 1 board?

autodeskguest

Is there a way to do this?

I have two different schematics but I want to use 1 universal board

Most of the parts are empty or values changed.

I cant think of a clean way to do it

Thanks

    Normal practice is to design the schematic as the super-set, but set the

    values of many of the components as "do not fit" or similar. You end up

    with a schematic which, at first sight, makes no sense - and often fails

    ERC because there are multiple output pins on a single net. However,

    it's a common enough technique and board populating houses are generally

    quite happy to handle parts lists with unfitted parts.

     

    What it doesn't do well is really different boards, or simple selection

    of which variant you're building. Your description suggests maybe the

    two circuits you want to build are quite different, so the usual trick

    may not suit, but it does work well for variants such as normally

    fitting an  RS-232RS-232 interface but having the option of RS-422 instead
