Five Pack Adjustable Buck Converter Module 3 To 40V In, 1.5 To 35V Out DC-DC Step Down Power Supply, Up To 3A, Includes Blue Potentiometer For Precise Output, Perfect For Prototyping, Makers, RC And DIY Electronics

Five-Pack Adjustable Buck Converter Modules: 3-40V In, 1.5-35V Out
✔️ Five LM2596 buck modules, 3A max, blue potentiometer for output

These five compact buck converter modules use the LM2596 regulator to drop higher voltage down to a stable, adjustable output. They're a staple for prototyping, makers, RC projects, and general DIY electronics where a small, affordable regulator is needed.

✅ Input voltage range: 3 V to 40 V (no boost; input must be at least 1.5 V higher than output)
✅ Output range: 1.5 V to 35 V, continuously adjustable
✅ Max output current: 3 A per module
✅ Includes blue potentiometer for precise voltage adjustment
✅ Pack size: five units, module size 45 x 20 x 14 mm

💡 What is a buck converter used for in DIY electronics? Buck converters are handy power regulators that reduce higher input voltage to a lower, stable output efficiently. - Handy for powering microcontrollers from battery packs or higher voltage supplies - Helpful for LED drivers, sensors, and RC components - Great for prototyping and hobby projects needing adjustable voltage - Low heat and better efficiency compared to linear regulators
