With this module, a Li-ion/li-Po battery can easily be charged with a solar panel (battery and solar panel are not included). If there is not enough sun, the battery can also be charged via the micro USB connection (micro USB cable is not included). In addition, the module has a built-in DC-DC converter that brings the voltage of the solar panel and/or the battery to 5V.

At the back of the module is a DIP switch with which the most efficient voltage of the solar panel can be set. This creates a simple form of MPPT.

Specifications:

  • Input voltage (solar panel output voltage): 6-24V DC
  • Output voltage: 5V DC (via pin headers and USB-A)
  • Maximum output current:
    • Solar panel (with sufficient power) only: ~0.7A
    • In combination with a (full) battery: ~1A
  • Battery charging voltage: 4.2V
  • Maximum charging current: 1A*
  • Maximum quiescent current module: <2mA

*Note: This is the maximum charging current of the charging circuit. Connected batteries may not be able to handle this current!

**Note: Normal AA batteries also fit in the holder, but do not insert them! This can lead to dangerous situations with fire, or even explosion, as a result. Only use this module in combination with suitable rechargeable Li-ion/Li-Po batteries that can supply sufficient power.
