###Addition if you want to do the buttons
### Addition if you want to do the buttons

The Badger uses the DSR# pin of the USB - Serial chip (FT232RL) as an input for the buttons. If you just want a single button (for editing label, for example), you can connect it directly to that pin (Pin 9), with the other side of the button connected to 0V.

If you want to have two buttons, you need a multiplexer. Pin 2 (DTR#) drives the selection. See the "BadgerMux - Schematic.pdf" for a sketch of a circuit which works.
