# History change playground 7ca2 ## Description This is a power management board which supports solar (4.4V - 6V), USB (5V) and Battery (3.2 - 4.2V) Supports battery recharging by either the solar or USB. The output should be 3.3V at 1A, 5V at 600mA and 12V at 500mA The project uses switching regulators and has 3 independent rails for the 3 outputs. #templates #iot #powermanagement ## Project Details -
