LM2596 DC to DC Buck Converter 3.0-40V to 1.5-35V Power Supply Step Down Module

Struggling with mismatched voltages in your electronics projects? The LM2596 DC-DC Buck Converter lets you step down any input from 3V–40V to a precisely adjustable 1.25V–37V output — all with a built-in LED voltmeter right on the module.

Built around the reliable LM2596 switching regulator IC, this module delivers up to 2A continuous current with high efficiency and low heat generation — far superior to linear regulators that waste energy as heat. What sets this version apart is the onboard LED digital voltmeter that displays either input or output voltage at the press of a button, so you always know exactly what's happening in your circuit. The voltmeter accuracy is even calibratable against your own multimeter, giving you lab-grade confidence in a compact module. The wide input range makes it compatible with solar panels, Li-ion battery packs, 12V/24V adapters, and bench power supplies alike.

This module is ideal for hobbyists, electronics students, Arduino/Raspberry Pi makers, and professional prototypers who need a reliable, adjustable power supply without building one from scratch. Whether you're powering sensors, motors, LED strips, or microcontroller boards, this converter handles it cleanly and efficiently.
