Which part for ends? [message #163359] Mon, 21 September 2015 09:18 Go to next message

Which Eagle part should I use when the end of a component goes to
nowhere (actually it does, but to another circuit which I'm not building)

or....

a schematic which has connections on the PCB without connectors (i.e.
cables are soldered directly to the PCB)?

Should I just leave the end of the nets in open air and label them with
a description, or should there be some sort of connection pin, circle,
arrow or whatever?

You're going to need a place on the board to connect the cable. It'd be
best to create a connector with an SMD or through-hole pad.

The connector symbol on the schematic would show the connection so some
external device, and should be noted as such.

Yes, that makes sense.
I found a library called "Wirepad" which seems to be what I need.

I've done some schematics which are extracted from a bigger one (i.e.
I'm working on just a specific section of the whole circuit).
Obviously I'm not going to make a PCB for this but I'm only developing
something. So I should add a connector part in this case to where it
attaches to the rest of the circuit, to keep it neat and tidy?
