The Optimus LM2596 Buck Converter is a compact, high-efficiency voltage regulator module designed to step down a DC voltage to a lower, user-adjustable level. It is based on the LM2596 switching regulator IC, which allows for efficient power conversion with low heat generation and stable output.

This module features an onboard potentiometer for output voltage adjustment, screw terminals for easy wiring, and onboard capacitors for filtering and stability. With a wide input range and up to 3A output capacity (with heat dissipation), it is ideal for powering microcontrollers, sensors, motors, and other DC-powered electronics in both educational and professional projects.
