That's it, before you close the case up, its good to do some testing (in case a wire is not soldered right, etc) Now is a good time to pair the Bluefruit to your computer and then test each button to make sure you're getting the key press you expect.
If you want to use it with a program that doesn't allow you to set the keys to the default Bluefruit keys, you can use the wireless remapping software to change the keys from the default to whatever key-presses you want
The lithium battery can be placed to the left of the bluefuit and mounted to the back cover with a piece of double-sided foam tape. Carefully place the switch inside of the cut out we made earlier and let it stick out a little so you can reach it. Now you can gently close the back cover, make sure to tuck and excess labels or wires inside of the enclosure. Place the Phillip screws back in and tighten it shut!
The part can be mounted to the back of the controller with a piece of double-sided foam tape. The holster is small and takes under ten minutes to print out. The holster nicely holds the USB micro lipo charger in piece.
