     Usually, you would add one two-pin connector, or two one-pin
     connectors, for the power connection.  There are a range of
     footprints
     available for this - if you just want to solder wires to it,
     HEADER2_1
     is sufficient - it's just two pins on 0.1" centers.


   Would this be done in gschem? Or in pcb?
   In gschem I have a symbol for gnd, and there is no footprint associated
   with it. There is another symbol for +5 V. Do I add a connector on
   gschem and use it instead of then GND/5V symbols? Or do I associate a
   footprint of HEADER2_1 with each of them? Or with one of them?
   Thanks for answering beginner questions!
