Solar Charger Shield for Arduino Solar Panel Solar Cell - OpenELAB

Solar charger shield boasts the features of collecting energy, power management, and charging, as a stacked shield and compatible with the UNO R3 control board. On this shield, BAT interface could output 5V when connected 3.0V-4.2V rechargeable batteries. At the same time, the USB interface connected to external power and SOL AR port connected to solar panel can provide power for external batteries. When the DIP is dialed to the ON end, external batteries or USB ports supply power to the UNO R3 board. Moreover, CH LED(red) is on when charging the external battery; OK LED indicator will be on if fully charged.
