MPPT SD05CRMA Solar Charge Controller for Li-Ion / Lipo Batteries

This solar charging module with the SD05CRMA chip charges a single-cell (3.7 V) Li-ion or LiPo battery from a solar cell. It accepts solar voltages of 4.4 V to 6.5 V and charges with an end-of-charge voltage of 4.2 V and up to 1 A. The charging current can be adjusted via resistor R1. Overcharge protection and an automatic sleep mode protect the battery. For solar panels with a higher voltage, a step-down module is connected upstream. The battery is not included.
