BooSTick – small AA voltage booster on Kickstarter
A single AA battery is used to provide 5V or 3.3V (or other voltages by tuning the feedback resistors). A boost regulator provides the “over”voltage. 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,…
