The LM2596 Step Down Buck Converter is a DC-DC converter module built around the LM2596S chip, switching at 150 KHz to step down an input of 4.0V–40V DC to a continuously adjustable output between 1.25V and 37V DC. The input must stay at least 1.5V above the target output for correct regulation.
Rated output current is 2A continuous, with a maximum of 3A when a heatsink is fitted, delivering up to 15W without additional cooling. Conversion efficiency reaches up to 92%. Onboard filtering comes from a 220µF 35V capacitor plus a 100µF 50V capacitor, paired with a 470 SMD inductor.
A 3-digit LED voltmeter display toggles between input and output voltage via a tactile push button, while a multi-turn potentiometer allows fine voltage adjustment. Screw terminal blocks connect both input and output sides.

5// LM2596 Step Down Buck Converter with Digital Display is set with its own onboard trimmer potentiometer (a small screw you turn with a screwdriver) - it has no digital control interface, so there's nothing for a microcontroller to do here. If you need SOFTWARE-adjustable output voltage, look at a digital-potentiometer-controlled design instead (e.g. this module's feedback pin driven through a TPL0501/MCP41010).
