SparkFun LiPo Charger Booster - 5V/1A

The SparkFun 5V/1A LiPo Charger Booster is a board with a built-in voltage converter that allows you to connect a 5V microcontroller to a lithium polymer battery LiPo. With this LiPo charger, you can easily recharge your single-cell LiPo batteries via USB. The board is very flexible in its design and can therefore be used for various mobile battery-operated Arduino projects.

Important Note: This is not a direct replacement for the SparkFun Power Cell, as the board uses a different IC. In addition, this board does not have undervoltage protection or other battery protection features, so we recommend using it only with batteries that have a built-in protection circuit.
