Buck Regulator, Vin 5-23V, Vout 0-16.5V 

This is a DC-DC Step Down Power Supply Adjustable Module With a LCD Display. The display; using STN liquid crystal display screen, can simultaneously display voltage and current on a blue background with white characters, has a wide angle and wide field of view. Th start button is used to adjust voltage, left button to reduced the voltage, and the right button to increasing voltage. By pressing the button once, you can adjust the voltage by increments of 0.04V, if you hold the button down for more than 1s, you can quickly adjust voltage.
