Automatic Solar Charging Circuit Board Module - Night Light Control Sensor - 3.7V

If you're into DIY electronics and solar projects, this little circuit board is handy.

It's an automatic solar charging and night light control module.

It runs at 3.7V.

Basically, it uses the solar panel to charge a battery during the day, and when it gets dark, the light sensor turns on your LED load automatically.

It's unbranded, but it's a common module for making your own solar lights, garden lamps, or small off-grid lighting projects.

Brand new, ready to wire up.

Good for tinkerers.
