USB Adapters

OK, now it's time to work on the USB adapters. Grab the USB OTG adapter and the USB female port (this came with the PowerBoost 1000C). We need to create a set of 4 wires that will connect these two components together.

This is necessary for connecting peripherals to the Raspberry Pi such as WiFi adapter, USB Audio adapter and more.

Remove Legs from USB Female Jack

Use a pair of flush snips to cut off the legs from the female USB jack. These prevent the port from being able to fit into the case. They're normally used to secure the jack to pins on a PCB, but since we're mounting to it the case, we don't need them.

Prep USB Pins

Next, we need to bend the four connectors on the USB female jack so they're right-angled. As they are now, it wouldn't fit in the case. Use a pair of flush pliers to carefully bend each connector. You'll want to be cautious while doing this. The connectors MUST NOT touch the metal housing - if it does, it'll short out the connection. You can optional remove the metal back piece from the USB jack.

USB Wires

We'll need to make a set of four wires for connecting our USB adapters together. I found 13cm to be a good length. Like we've done previously, strip and tin the ends of each wire. A piece of heat shrink tubing will keep these four wires together.

Connect Wires to USB OTG Adapter

Most microUSB cables follow the same color coded wiring. 

  • Black / Blue – GND
  • Red – VCC 5V
  • Green – USB Data -
  • White – USB Data +

Follow the photo to reference which wire to connect to the correct pin. Tinning the four pins on the USB OTG adapter will make it easier to solder the wires to them.

Connect Wires to Female USB Jack

Following a similar method, connect the four wires to the pins on the Female USB jack. Note the colors are reversed. That's because we have the USB jack fliped. Make sure you familarize yourself with the top and bottom of the USB jack. The bottom has the white plastic bit.
