Converts 4–35 V down to any voltage from 1.25 to 30 V at up to 3 A — power 5 V boards from 12 V batteries or solar panels.

The LM2596 converter efficiently steps a higher voltage down to the level your electronics need — for example 12 V from a car or solar battery down to 5 V for an Arduino or 3.3 V for sensors. Turn the brass potentiometer to set the output while measuring with a multimeter. Switching operation wastes far less energy than a linear regulator.
