This is a mini Solar LiPo charger based on the CN3065 - a single lithium battery charge management chip, which provides the ability to get the most possible power out of your solar panel or other photovoltaic device and into a rechargeable 3.7v LiPo battery. As an alternative it is possible to charge the battery by using the Micro-USB Connector included in the board.
By default, the battery charge comes set to a maximum charge current of 1000 mA with a maximum recommended input of 6V and a minimum 4.4 V.
It's recommended that batteries not be charged at greater than their capacity rating, for this reason we suggest to use this module with 1200 mAh LiPo batteries or greater.
