RFduino - Dual AAA Battery Shield
This is the RFduino Dual AAA Battery Shield, a long add-on board for the RFduino DIP module that supplies 3.3V to your whole project. This shield can easily attach anywhere on your RFduino stack and will still be able to provide reliable power throughout each board.
The Dual AAA Battery Shield is also equipped with a power switch and a step-up switching regulator which allows the batteries to be drained down to low voltages while still providing a stable 3.3V to your RFduino.
Note: AAA batteries are NOT included with this shield but can be found in the Recommended Products section below.
- Output Voltage: 3.3V
- Output Current: 100mA
RFduino - Dual AAA Battery Shield Product Help and Resources
Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Be aware that the mounting of the little teeny power switch is pretty delicate. So be careful when you are handling this module.
It would be nice if the battery clip could mount under the board so you could stack the other boards and still slip it into a flashlight or other tube (like a PVC pipe).
A potential problem that I see with this board is that the supply voltage is exposed on two long, bare headers pointing downwards. Make sure you don't place it near metallic objects or near messy wiring because the short circuit risk is quite high. The designers really should have gone for female sockets only on this shield since it's bad practice to use male connectors on the supply side. I recommend trimming those pins.
