Adafruit BooSTick - AA Voltage Booster

The BooSTick from Rover Development revolutionizes portable power for your projects. It utilizes a single AA battery to deliver a selectable breadboard voltage of 5V or 3.3V, while a boost regulator handles the voltage regulation.

Its compact design, roughly the size of an AA battery, ensures easy integration into Arduino, wearable tech, and other DIY setups. With 200 mA output, it's ideal for powering microcontroller or analog projects without the hassle of cumbersome wires.

When the battery depletes, simply swap it out or opt for NiMH rechargeable batteries to minimize environmental impact. The BooSTick is perfect for prototyping and testing, fitting directly into your breadboard or even some Arduino boards with a smaller footprint than a standard shield.
