Port Description:
PWR IN:4.4~6V power input terminal. You should connect it to a solar battery. The maximum output
voltage of the solar battery should be in the range of 4.4V to 6V.
BAT: Connect a 3.7V lithium battery, for storing electricity.
VOUT: Lithium-ion battery output. Connect your electrical equipment to it.
Charging Indicator: When there are no battery, the green LED is ON and the red LED is flashing.
When charging, only the red LED is ON. After the charging is completed, only the green LED is ON.
FAQ
Q. Can I charge my lipo with a battery, and charge an arduino at the same time?
A. Not recommanded! For the Solar cannot produce a steady current generally. If you supply
the not steady power to an Arduino card, it may cause unexpected result or get the
bootloader lost.
