How to Use Solar Panels to Power the Arduino

Trickle charge (battery reconditioning) – the voltage level of the connected battery is less than 2.9V. Also, the module will use a trickle charge current of 130mA until the battery voltage reaches 2.9V. At that point, the charge current will be linearly increased to the configured charge current. Soft-start protection – limits in rush current.
