Add Bluetooth capability to your Raspberry Pi with this super fast USB BT 4.0 module. Utilising the CSR8510 chipset, this adapter is backwards compatible with v2.1 and earlier, but also supports the latest v4.0 low energy bluetooth transmission.
Revision note: As of Friday, August 28th, 2015 these now have unique MAC addresses! That's great because now you don't have to worry about using two or more of them at once, handy for people turning these into beacons.
Drivers for CSR Bluetooth modules are built into Windows XP/7/8 so you do not need to install any software or download anything: other bluetooth drivers or 'stacks' such as BlueSoleil are not as good as the Windows stack and will cause problems. Just plug it in and let windows auto-install the BT driver! For Linux (Raspberry Pi), use Bluez which works great, simply follow the tutorials below!
