DFRobot DFR0535 Sunflower Solar Power Manager
DFRobot DFR0535 Sunflower Solar Power Manager is used for high-efficiency micro to middle power solar energy harvesting and management. This solar power manager features Maximum Power Point Tracking (MPTT), which maximizes the efficiency of the solar panel. The DFR0535 module can provide up to 2A charging current to a 3.7V Li battery with an AC adapter or USB charger. This solar power manager also employs various protection functions such as Li battery protection, battery/solar panel reverse connection protection, output over temperature, and current protection.
