MPPT Solar Power Management Module for 6V-24V Solar Panel

The module from Waveshare charges a 3.7 V Li-Ion battery from a 6 V to 24 V solar panel or via USB and delivers regulated 5 V at 1 A on a USB socket and on the pin header, plus 3.3 V. The MPPT control draws as much power as possible from the panel. A holder for a 14500 battery sits on the board, another battery can be connected to the PH2.0 connector. The battery is not included.

Caution: Do not insert non-rechargeable batteries into the holder. Attempting to charge a non-rechargeable battery risks serious consequences up to an explosion.
