Step 5Soldering the power supply connectors
We now need to create a way to connect the Power Supply board to each of the sensors. Grab your power supply board, the four sets of wire lengths, and the female housing and receptacles.
On the Power Supply board, there is a grid of through holes in a 3 col x 4 row pattern. Solder the three 3" wires to the holes in row 1, solder the three 2" wires to the holes in row 2, solder the three 1" wires to row 3, and solder the 4" wires to the holes in row 4.
Next, grab your 3 female receptacles and bend all the solder tabs so that they're at a 90 degree angle. For the 1"-3" wire sets, solder the female receptacles (with the ports facing downward) such that the wire soldered to the +5V column is soldered to the right solder tab, the GND wire is soldered to the middle solder tab, and the -5V wire is soldered to the left solder tab. For reinforcement, dab a glob of hot glue on the joints.
Using a crimping tool (you can also choose to solder instead of crimping), crimp the crimp tips to each of the 4" wires with the tabs pointing upward. Now insert each of the wires' crimp tips into the female housing, again following the +5V right, GND middle, -5V left order.
Your power supply board should be ready to go. double check each solder and crimp to make sure they'll good and solid.
