5Pcs LM2596 DC Buck Converter Voltage Regulator, High Efficiency Step Down Power Supply Module 3.0V 40V Input to 1.25V 35V Output, 3A Max Current for DIY Electronic Projects

Package Include: Contains 5 pack LM2596 DC-DC buck converters, measure 44 x 21 mm (including the potentiometer). These step-down power modules are designed to meet your power adjustment needs, making them a practical set for various electronic projects. Premium Material: Each module is constructed with a sturdy PCB board, ensuring stable performance and durability. With a compact and space-saving design, ideal for fitting into small enclosures or tight project setups, without adding unnecessary bulk to your electronics. Easy to Use: Connect it to a power source, monitor the output with a multimeter, and adjust the potentiometer—rotate clockwise to increase voltage or counterclockwise to decrease it. The factory default is set to 18V, so you’ll need to turn it counterclockwise 7-8 times before the voltage starts to drop. Wide Use: Ideal for DIY electronic projects and small device setups. Whether you’re powering sensors, LED lights, small motors, or custom circuit boards, it handles various power adjustment needs, making it a handy tool for hobbyists and electronics enthusiasts. Output Details: This module supports adjustable output voltage and a maximum output current of 3A. Note that it functions only as a step-down converter—no boost capability. For stable operation, the input voltage must be at least 1.5V higher than the desired output voltage, ensuring reliable power conversion for your projects.
