LM2596 2A Buck Step-Down Power Converter Module DC 4 ~ 40 to 1.3-37V LED Voltmeter

The LM2596 2A Buck Step-Down Power Converter Module is a high-efficiency DC-DC voltage regulator that converts a wide input voltage range (4V to 40V) down to a lower adjustable voltage (1.3V to 37V). It is based on the trusted LM2596 chip and features an integrated 3-digit LED voltmeter display that provides real-time voltage readings without needing an external meter.

This module is ideal for applications that require reliable voltage step-down functionality in compact and portable formats. With a built-in precision multi-turn potentiometer, you can fine-tune the output voltage for your specific needs. Whether you’re powering sensors, modules, battery packs, or small devices, this module offers simplicity, accuracy, and flexibility.
