ADIY LM2596 Adjustable Module

The ADIY LM2596 Adjustable Module is a high-efficiency DC-DC step-down (buck) power supply module designed to convert a higher DC voltage into a stable, lower adjustable output voltage. Based on the reliable LM2596 switching regulator IC, this module can deliver up to 3A output current with excellent efficiency, making it ideal for powering microcontrollers, sensors, motors, and DIY electronics projects.

With an onboard multi-turn potentiometer, users can easily adjust the output voltage to meet specific project requirements. Its compact size, robust performance, and built-in protection features make it a favorite choice for hobbyists, engineers, and students.
