DC DC Buck Converter LM2596 with Display

Description of DC DC Buck Converter LM2596 with Display   This is a DC/DC step-down voltage regulator that converts input voltage between 3.3V and 40V into a smaller voltage between 1.25V and 35V, capable of driving load with excellent line and load regulation.    In some projects, you might need different voltages (3.3-35V) for your devices. Without this kind of DC power source, you’ll find it time-consuming to buy a new one. The delay of project is so annoying. No worries! This module can accelerate prototyping, because you can get the voltage you need (such as 3.3V, 5V and 9V) as easy as blinking eyes.
