This solar charger is a stackable shield for Arduino boards. A simple and easy way of taking your Arduino project off the grid! The Solar Charger Shield connects to a solar panel and a rechargeable battery. The shield handles all the charging and discharging of your lithium ion battery. You may use various batteries that has the voltage of 3.0V-4.2V to shift up for 5V output, or connect a rechargeable Li-ion battery and a solar panel to form an autonomous sensor unit. Features: Short circuit protection Max 3W (5V 600mA) output when battery is connected Continuous Charge Current Up to 900mA Battery status indication ( Red : Charging , Green: Charged ) Micro-USB port to charge battery Specification: Battery input voltage: 3.0~4.5V USB input voltage: 4.75~5.25V Solar input voltage: 4.8~6V Maximum Output Power(with battery): 3W(600mA@5V) Ripple voltage:
