Sunflower Solar Power Manager

DFRobot Sunflower Solar Power Manager is used for high-efficiency, small-power solar energy harvesting and managing low-power applications and IoT projects. The Sunflower is designed for a 5V solar panel and features an MPPT (Maximum Power Point Tracking) function. This maximizes the efficiency of the solar panel. The module can provide up to 900mA charging current to 3.7V Li battery with USB charger apart from serving as a solar charger. The ON/OFF controllable DC-DC converters with 5V 1A output satisfy the needs of various solar power projects and low-power applications. The module also employs various protection functions, like battery/solar panel reverse connection protection, output over temperature, and current/short circuit protection, which greatly improves the stability and safety of the system.
