LM2596 Step Down Buck Converter Module with Display

The LM2596 Step-Down Buck Converter Module with Display is a high-efficiency DC-DC voltage regulator that allows you to convert a higher DC voltage to a lower one with adjustable precision. Equipped with a built-in 3-digit voltmeter display, it provides real-time voltage monitoring for both input and output, making it ideal for lab use, DIY electronics, and embedded system prototyping.

Powered by the reliable LM2596 buck regulator IC, the module supports an input voltage range of 4V to 40V DC and delivers an adjustable output from 1.25V to 37V, with a maximum output current of 2A to 3A (with proper cooling). Voltage adjustment is done via the onboard multi-turn potentiometer. A small push button toggles the display between input and output voltage readings.

This module is perfect for powering Arduino, Raspberry Pi, LED strips, routers, motor drivers, and other 5V or 12V electronics from variable power sources like batteries or solar panels. Whether you’re building a regulated power supply or fine-tuning voltage for delicate components, the LM2596 with display offers a practical and visual solution.
