This is a standalone Lithium battery charger which lets you charge up your batteries from a micro USB cable. The battery can connect to a JST SH connector (the battery connector on the batteries that we sell at TinyCircuits). You can also use this without the JST connector with two large through holes to connect to a battery pack.
Simply plug the USB side with a cable into a USB port, and plug a lithium polymer or lithium ion rechargeable (3.7V / 4.2V) battery into the other side and it will start charging. A status LED on the board will indicate when charging, and will turn off when fully charged.
Note: The battery and the microUSB cable are not included.
