Product description: DFRobot Solar Power Module with 2 V / 160 mA cell

This module allows you to charge a 3.7V Li-pol battery with the included mini solar cell or microUSB port and power your devices with 3.3V. Included is a cable with JST plug to connect the battery and two double goldpin plugs and wires to solder the photovoltaic panel. All modules in this series have theMPPT algorithm (maximum power point testing of the panel) which greatly increases efficiency under changing conditions. The board is also equipped with a number of protections - against overcharging, over-discharge and reverse battery connection as well as against short-circuit and too high load on the 3,3 V output.

Description of the module pinouts.

Examples of use

The module was designed for powering IoT devices and small projects using renewable energy. Thanks to 3.3V output it can successfully cooperate with most of sensors or more complex systems. The battery acts as an energy buffer during the work of connected components, which is supplemented by solar panels during their rest time.

Buffer power supply for an example sensor using a panel and battery.

Using the module as a USB charger for 3.7V li-pol batteries.

I got different solutions for the power supply of my IOT project. The solar panel from DFRobot looks good and does its job. The price is higher than other products, but seems okay.
