BooSTick provides extremely small and convenient portable regulated power to Arduino, wearables, DIY, and other projects. The entire package is about the size of a single AA and can drive Arduino projects for many hours at a time. When the battery is used up, pop another in for continued use. Or use NiMH rechargeable batteries to reduce your footprint.

Voltage outputs:

3.3 V (with jumper installed)
Pull the jumper for a full 5V supply! (included)
Other voltages between 1.8 V and 5.5 V are achievable by tuning the feedback resistors. Specify different voltage if desired.

Current limit (with new batteries). Battery will only last minutes at these levels:

5V: 220 mA
3.3V: 320 mA

Run time:

5V, 50 mA: 6 hrs
3.3V, 50 mA: 12 hrs
Lower current/voltage generally leads to proportionally longer run time or more

Indicators:

Green power on LED
Red low battery LED
