## Overview

The SunRobotics LM2596 DC-DC Buck Converter is a versatile power supply module designed for efficiency and safety. With an input voltage range of 4 to 40V and adjustable output from 1.25 to 35V, it caters to a variety of electronic projects. Its robust design supports up to 3A output with thermal protection, making it ideal for both hobbyists and professionals.

## Description

This is LM2596 2A Buck Step-down Power Converter Module DC 4.0~40 to 1.3-37V, it comes with a built-in voltmeter display and uses an advanced microcontroller. This version of LM2596 DC-DC step-down (buck) power supply module includes the very useful addition of an integrated digital voltage meter. The voltage meter is capable of sensing both input and output supply voltages and can be quickly switchable between the two by pressing a voltage selection button on the module. Together with its high precision multi-turn potentiometer, this means any desired output voltage within its supply range can be set without the need for an external voltage meter. The module also boasts a very high operating range with a DC input supply range of 4 – 35V and an adjustable output range of 1.3 – 35V. In addition to its voltage range, it has a high output current capability of up to 2A. Connection to the module is provided with the option of both input and output screw terminals or large solderable pads if a more permanent connection is required.
