MCP73871 Solar Lithium Battery Charging Module DC 5V

MCP73871 charge contoller

This MCP73871 solar power management module is designed for 5V to 6V solar panels. It can charge the 3.7V Li battery via solar panel. The scope of delivery also includes a large stabilizing capacitor that still has to be soldered onto the board. The module is an inexpensive option to supply your outdoor IOT projects with solar power.

Info: There is not much documentation about the board yet.
