    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

    • can I use this together with the compatible solar panel and li-on battery to power my arduino with gsm shield, pH sensor, turbidity sensor, & temperature sensor and make it a standalone project?

      I need 25 charger circuits . Is that circuit good to charge from 5V@1A solar panel to charge single cell 3.7V 10-12 Ah LiOn battery ?

    • Can I charge my lipo with a battery, and charge an arduino at the same time？
      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.
