This is a really simple USB breakout that I made in half an hour so that I could control some USB powered Christmas lights with an Arduino and a relay module.

There are three ways to connect the USB with this board:

Solder wires to the strip board
Connect to male header pins
Connect to female header pins

Step 1: Parts Required

You will need:

Parts

A small piece of strip board (At least 4x5 - 4 strips, 5 holes)
A female USB jack - I took mine of a broken USB hub
4 pin male header strip
At least 4 pin female header strip - we can cut this down to 4 pin later

Tools

Soldering iron
Side cutters
Glue gun (optional)

Step 2: Soldering the USB Jack

First, check the USB jack fits on the strip board. If the strip board to too wide, trim it down with the side cutters but make sure you leave four strips for the USB pins. n.b. the two bigger pins you can see in the photo don't need to be soldered.

If you have a glue gun and want to make the attachment of the USB jack to the strip board stronger, squirt a little hot glue under the jack, but make sure you don't cover the ends of the pins or else it will be harder to solder them onto the board.

Once everything fits, solder the four pins to the strip board. To learn how to solder, go here.

Step 3: Preparing the Header Pins

For the male header pins, snap 4 off from a strip.

For the female header pins, use side cutters. Align them so the cutting edges are along the centre of the fifth pin. You will break this pin and get four female header pins as shown in the last image.

Step 4: Adding the Header Pins

If you have a glue gun, squirt a bit of hot glue on the female header pins as shown in the first image. Quickly put this in the strip board before the glue cools. This will stick the header pins to the USB jack to make to whole unit stronger and more robust.

First solder the female header pins and then add the male header pins and solder these.

You can snip the any excess strip board that you don't want with side cutters but remember to leave some if you either want to screw you board to something or want to be able to solder directly to the board later.

Step 5: Finish

You now have a USB breakout board which you can connect to using male or female connections or soldering wires onto the holes in the strip board at the end.

Refer to the diagram to see which pins you need to plug in to to con

With the USB jack facing you

The left pin is VCC. This is the voltage input - 5V for USB
The 2nd left pin is Data - (used for communication)
The 3rd along is Data + (used for communication)
The right pin is GND. This is the negative voltage terminal.

For more information about how USB communication works, I found this article useful: USB Overview

If you just want to power something like my USB fairy lights, you only need to connect VCC and GND.

n.b. Just connecting VCC and GND won't work for changing some devices. For example, iPhones won't charge because you need to connect the Data + and Data - pins with resistors. If you want to charge an iPhone, go here.
