Place the Raspberry Pi A+ over the bottom enclosure and line up mounting holes with the stand-offs. Line up the USB port with the cut out near the edge. Hold the Pi down and fasten four #4-40 flat Phillips machine screws to each stand-off.
We'll be working with male/female jumper cables for most connections that interface with the Pi's GPIO header.
Using jump wires will allow us to quickly plug or disconnect cables from the GPIO. This is a thinner approach then using the Pi Cable - You can also easily decipher connections by using colored wires.
To make "super thin" jumper cables, all we need to do is remove the covers and bend them a bit. Here's the breakdown:
Remove the plastic covers from two female to male jumper cables and snip off the male connector. Strip and tin the end of the wire. Carefully bend the female connector from the jumper cable to make it a right angle plug. Check the length of wire and ensure it reaches powerboost +postive and -negative pins.
Place a small piece of heat shrink tubing over the wire to insulate the exposed female jumper connector.
Solder one jumper wire to the 5V pin on the PowerBoost. Solder the other wire to the GND pin.
Plug the jumper wired to 5V pin on the Powerboost 500C to the 5V (Pin #2) pin on the Raspberry Pi.
Connect the jumper cable wired to the GND pin on the PowerBoost 500C to the GND (Pin #6) on the Pi.
Now we can easily unplug the cables from the Pi and remove it if we wanted to - This project is all about being modular!
