BooSTick – small AA voltage booster
BooSTick has captured imaginations around the world and has been featured on some really cool international online blogs and magazines!
Slightly larger than a AA battery with holder, but supplies higher voltage for anything!
This tiny board allows you to bring the power to your project, and not the other way around. Bring your micro to the sensor without running wires! A single AA battery is used to provide breadboard power of 5V or 3.3V (or other voltages by tuning the feedback resistors). A boost regulator provides the voltage.
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.
What can I do with a BooSTick?
I’m glad you asked!
Prototyping: Since BooSTick plugs right into your breadboard, you can use it for prototype power and testing.
Wi-Fi: Even Wi-Fi is possible with the BooSTick. The ESP8266 draws a bit of a current spike at some point in its operation, so a cap is required on the power supply to keep the BooSTick from dropping out during operation. With the cap, Wi-Fi runs great!
Arduino: BooSTick plugs right into some Arduino boards and provides power in a footprint smaller than a standard shield.
At 5 V, 200 mA output, BooSTick can handle even the biggest Arduinos. Even if you’re sloppy with power management in your code and you use a power hungry shield, you can use two BooSTicks in parallel to provide even more than 200 mA. Or better yet, connect a two battery AA holder to achieve more than 550 mA at 5 V. That’s enough to charge a cell phone!
LED lights: I’ve used the BooStick in a POV (persistence of vision) project where I needed an untethered power source to put my electronics in a bike wheel: https://hackaday.io/project/6470-multi-sensor-pov-light
