This is the RFduino CR2032 Coin Battery Shield, a small add-on board for the RFduino DIP module that supplies 2-3V to your whole project. This shield can easily attach anywhere on your RFduino stack and will still be able to provide reliable power throughout your boards.

The CR2032 Coin Battery Shield is also equipped with a power switch and, unlike the AAA Battery Shields, directly powers the RFduino without any regulation.
