Description

The LM2596 Buck Converter Module is a compact DC-DC step-down regulator that allows you to efficiently convert higher DC voltages to lower ones. It provides an adjustable output voltage from 1.25V to 35V with input voltages up to 40V, making it suitable for powering Arduino boards, ESP32 modules, sensors, LED strips, and battery charging applications.

Built around the LM2596S switching regulator IC, this module delivers up to 3A output current and features an onboard potentiometer to fine-tune the output voltage. The power and output LEDs make it easy to monitor operation. It’s widely used in embedded power systems, robotics, and portable electronic designs where energy efficiency is critical.
