Remember the Mintyboost? Oh yeah – it’s a nifty project. But Adafruit has engineered this finished module to slide into the same application, which is to take a low-voltage source, and turn it into a nice 5.2V power supply, with benefits.

First of all, why 5.2V instead of a solid 5V? The extra 0.2V will adequately compensate for any connector and cable losses between this module and the project you are powering. Even so, feeding 5.2V into a “5V” designed device is quite safe. Feel comfortable using this to power your Arduino / RaspPi / BeagleBone / etc…

Specifications:

• 2A Switching capacity. This means you can get at least:
  • 500mA from a 1.8V source,
  • 750mA from 2 AA alkaline/rechargeables,
  • over 1A from a 3.7V LiPoly/Li-Ion or 3-cell battery pack!
• 3.2V Low battery indicator, which is ideal when using LiPoly/Li-Ion cells
• 500mA charge current Apple/IOS resistor settings
• Full pin breakout for the battery, enable, control, and power out lines for embedding onto a breadboard
• 90% operating efficiency in most operational conditions
• 5mA quiescent current (doing nothing), and 20uA current in disabled mode
• Included optional USB A jack for turning it into a USB power-point
• Includes footprint for using a 3.5mm 2-pin terminal block
• 28x22x2mm (1.1×0.9×0.08″), 7mm high (0.3″) with JST header
• Weight: 3g
