A way to add power to your Wemos D1 mini based projects in a flexible manner. It has a battery charger and options to add various 5V regulators.
Till recently there were no decent power shield options for the very popular Wemos D1 mini. So I designed my own. It combines a voltage regulator with a battery charger making it possible to power the Wemos from solar panels or 12V car systems.
This module is very compact and flexible. The user has the option to choose which voltage regulator to use - 5V dc-dc buck for high efficiency, 5V Ldo for operation with variable voltage input such as solar panels or the time honoured 7805 for a very low cost solution.
