The USB LiPo Charger is a basic charging circuit that allows you to charge 3.7V LiPo cells at a current of 500mA or 100mA. It is designed to charge single-cell Lithium-Ion or Lithium-Polymer batteries. Check the datasheet below to see if it will work with your battery.
The board incorporates a charging circuit utilizing a Microchip MCP73831T, status LED, selectable solder jumper for 500mA or 100mA charging current, external LED footprint, USB input, mounting holes, and various holes for your own connectors. A loose JST-type connector is included which you can solder onto the board if you're using batteries with the matching type of connector.
There is also a SYS OUT area which allows you to connect the charging circuit directly to your project. In this way, you won't need to disconnect the charger each time you want to use it.
