No Connect Symbol

autodeskguest

Does EAGLE have a no connect symbol to assign unused pins on the

schematic?  Whenever I run an ERC it throws allkinds of warnings for

unconnected pins.  Although not a show stopper, it does become annoying

at times.

    No, but there's no reason you couldn't make one. Or you could use a test

    point. That will create an object on the board, but it could be just a

    tiny copper dot, which is hardly a major issue.

    Yes, I've had that. In one specific case (a thermocouple amplifier) that

    has pins for two "unused" resistors, I just put the resistors on the

    schematic with a value of "do not fit".

     

    However, you should be aware that Eagle normally only complains about

    pins that are marked on the library component so as to suggest that it's

    probably bad practice to leave them floating. If the pin is explicitly

    marked as an output, Eagle won't usually object. If it's an input then

    it shouldn't be left floating.
