Sure hifi AUX APT-X Bluetooth 4.0 board case

thingiverse

This is a case I made to hold an APT-X Bluetooth receiver board with audio outputs. I started this project looking for a way to add a good quality audio Bluetooth connection to my car, which only has Bluetooth connection for calls and a spare aux in. Audio output goes automatically through this board and calls through the native car connection. The board needs a power adapter (I used a 12v direct connection to the cigarette lighter). The board I bought is this one: http://www.ebay.com/itm/112427004167 I am very happy with overall quality. Just keep your Bluetooth volume in phone not too loud and the output is loud and crisp. Small 2mm wood screws fit fine in this. Hope this case is useful for someone. My first share!
