Step 12Required Assembly: Jumper Points
Now that you have your workspace covered with about 36 small pieces of wire removed from the resistors, we are going to put some of them to use. In the picture of the UPCB below, I have labeled the three points we are going to jumper with wires.
The two points marked 'VCC TEST' and 'GND TEST' are simply points set aside for troubleshooting. When testing a board, it is very handy to have convienent locations to connect your tools for the power and ground. We will run some tests in the next step that use them, so let's get them ready.
Take one of the discarded legs, and bend it in a loose 'U' shape. Insert the two ends into both holes of the 'VCC TEST' location. Unlike the resistors before, we do NOT want the wire flat against the board. We want to leave a little loop that an alligator clip or hook probe can latch on to securely. We don't want it sticking out so far it will bend and touch other components. Use your best judgement, and when it is at the height you want, bend the legs to secure it in place, and solder it. Trim off any excess wire, and repeat with the 'GND TEST' point.
The third point is not well identified on the UPCB silkscreen, but marked in the upper left of the picture below. All power from the console must first past through there. Take one of the discarded legs, place it through the two holes and lay as flat as possible. You do NOT want this touching any other components, and you do not need to leave a loop like you did with the test points. Bend the legs in place to secure, solder in place, and trim off any excess wire.
In the picture below, you can see the two test points I made, along with a hook probe hanging onto one. You can also see a jumper on two pins where you made the last jumper connection. This gives me a place to interupt the power to the UPCB, and place a multimeter in the way so I can measure the amperage of the board when needed. If you understand what that means, this is an option you can do as well, but I expect most people will just jumper the board and forget about it.
