XL4005 5A DC-DC Buck Converter Module - Adjustable Voltage (0.8-30V) CC/CV For Charging & Arduino

Need a versatile, powerful DC-DC step-down (buck) converter for your projects? This XL4005 module is a workhorse. It can take a higher DC input voltage (up to maybe 32V+ input, but check specs) and output a clean, adjustable voltage from 0.8V all the way up to 30V, with a max current of 5 Amps. It features Constant Current (CC) and Constant Voltage (CV) modes, making it perfect for charging Lithium-ion batteries, powering LED strips, or serving as a lab bench power supply for Arduino, Raspberry Pi, and other electronics. Brand new, generic, from China. Just hook up input and output wires, turn the potentiometers to set your desired voltage and current limit. A must-have for any serious tinkerer's workshop.
