Description
The solar charger is a stackable shield to Arduino compatible platforms, enables adaptive battery power and act as energy harvester for in-field charging.
You may use various batteries that has the voltage of 3.0V-4.2V to shift up for 5V output, or put on Li-ion battery and solar panel to form an autonomous sensor unit.
The maximum current provided by the board can get up to 600mA. An usb connector is also useful to charge the battery.
Features:
Output Disconnect
Short circuit protection
3W Output Power when connecting battery
Continuous Charge Current Up to 900mA
Battery status indication ( Red : Charging , Green: Charged )
Micro-USB Connector
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：
