Single USB Boost + Lithium Charge Controller Board
Why deal with two different boards when you can just use one? This little board features the combined power of our USB Charge Controller and our Lithium Charge Controller Boards. All in one very cute package.
To use, just solder in a 3.7V Lithium Battery of your choice. Use the built in Mico USB Port to charge the Lithium Battery, and the standard sized USB port to charge up a gadget.
Features a button activated 4 LED charge status on the bottom that shows how much power your battery has.
You can easily modify this board for use with a solar cell. (Actually you'd just need to solder a micro USB cable to your solar cell. It's surprisingly easy to do.)
