It is based on a XL4015-family step-down voltage regulators, - recommended for up to 3A continuous -  supporting input of 4-35V DC and output of 1.25V-36V.\u003cbr\u003e\u003cbr\u003eOn a regular buck converter, there is no display and you have to measure the output manually with a multimeter which can be slow and inefficient. This buck converter has a display with the output voltage readout integrated into the board. You can change the output by adjusting a screw potentiometer that is also integrated into the board.\u003c\/p\u003e\n\u003cp\u003eThis module can be used in DC applications such as batteries, power transformers, DIY adjustable power supplies, 24V vehicle power supplies, industrial equipment, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V and so on.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note that the potentiometer can sometimes be set a little high in the factory and may need a lot of anti-clockwise turns to get it to start dropping the voltage. \u003c\/strong\u003eOnce you have it set around that correct area, it'll work just fine!\u003c\/p\u003e\n\u003ch2\u003eSelf-Calibration\u003c\/h2\u003e\n\u003cp\u003eThe onboard voltage meter supports self-calibration mode. You only need to calibrate it once and the value will be stored automatically. The method is as follows:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHold the button for 3 seconds.
