The Bluefruit LE Shield makes it easy to add Bluetooth Low Energy connectivity to your Arduino or compatible. Solder in the included headers and plug right in. It connects to your Arduino or other microcontroller using the hardware SPI interface (MISO, MOSI, SCK) plus a chip select line (default D8), interrupt line (default D7) and reset (default D4). You can rearrange any and all the pins if you'd like, by cutting the jumpers underneath, and soldering jumper wires to your desired pins.

Easy setup by following the tutorial
I purchased these to use with RGB rings. I used the tutorial supplied on the manufacturers web site and the example programs. I installed the app for my tablet and phone and everything worked great. Then I found I could also control the color of the rings from my watch. I plan to use them in several projects.

These are high quality bread boarding for those projects to be made permanent.
