Adafruit PowerBoost 500 - Basic
Get 5.2V USB-style power @ 500mA from as low as 1.8VDC
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...
- 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 (1.1x0.9x0.08"), 7mm high (0.3") with JST header
- Weight: 3g
