Gestionnaire d'alimentation solaire 5V, PowerBoost

Power up you 5V project from solar energy with this solar power management module

The Solar Power Manager from DFRobot is designed for IoT and renewable energy projects. it provides a high efficiency solar power management module, a great add on for Maker and IoT projects.

This module is small and easy to use. It will be great to create Solar Power Bank or solar environment monitors. It can energize low-power application from a solar panel.

Solar Power Manager 5V is designed for 5V solar panel. It features as MPPT (Maximum Power Point Tracking) function which maximize the efficiency of the solar panel. The module can provide up to 900mA charging current to the 3.7V LiPo with an USB charger or solar panel. The module also offers various protection features for the battery, the solar panel and output which improves the stability and safety of solar powered projects.

The BAT IN (battery) is protected with over-current and over-discharge protection.

The DC/DC converters can provides up to 1A @ 5V output power. The DC/DC converter is controllable and can be switched on/off depending on needs.
