Step 8Extra Buttons
If you want to have the two extra buttons available for play, you'll need to connect them to the UPCB board. Each of the two buttons has two wires; one needs to go to ground, and the other to either RA0 (the top of the two) or RA1 (the bottom of the two). You can choose to solder them directly to the spots on the board, but this is rather sloppy.
The way I chose to go is to use standard .1" headers and connectors. In the first picture below, you can see the headers installed on the UPCB. Each button has two wires going to a two pin connector that slide right onto the headers.
Place the header on the connector, put the quick disconnects onto the buttons, and secure the extra button wires to the collection of wires going to the IDC connector with zip ties. The buttons on mine won't be used, so I stashed the four wires in one of the size cubby holes of the HRAP case in case I decided to install the buttons in the future.
The one marked RB5 is the optional programming button. We'll be covering that next.
