Assemble a Universal PCB

Step 27 Optional Assembly: Piggyback Option

This step covers the parts needed for using the Piggyback function of the UPCB. There are two 16 pin IDC connectors, and one 14 pin IC socket. This step is completely optional. For systems that the UPCB doesn't natively support, the Piggyback function allows you to connect a hacked controller from that system side-by-side with the UPCB, and use it as if it were natively supported. It is expected that the Dreamcast and Xbox360 will be the most commonly used consoles for Piggyback'ing.

Start with the IC socket. Just like the 40 pin socket we did in the beginning, there will be a notch on one end of the socket to mark the first pin. You will see a matching notch in the silk screen on the UPCB. Place the IC socket so that the notches match, and solder a single corner pin. Check to make sure the IC is lying flat. If the socket needs adjusting, melt the solder and adjust. If the socket looks good, solder the opposite corner and check again. Once the socket has two soldered pins and the socket is resting fully, go ahead and solder the other 12 pins.

Next we'll do the two 16 pin IDC connectors, into the spots labelled 'DC Connector' and 'X360 Connector'. The steps for both are identical. Place a 16 pin IDC connector into the spot marked, with the small key notch facing the inside of the UPCB. Solder one of the corner legs in place. Check to make sure the IDC connector is resting flat against the UPCB. If the conenctor needs adjustment, melt the solder and adjust. Once it has cooled, solder the opposite corner pin, and test again. Once the connector is flat against the board, and two pins are soldered, go ahead and solder the other 14 pins. Repeat for the other IDC connector.
