✍ With this XL4015 module, you can monitor your project much more easier. The voltage meter can measure the input voltage or output voltage, which is adjustable by the protentiometer, with a precision of ±0.1V. Note that the voltage meter would not work if the input voltage below 4V. Press the button (right) to switch voltage to measure, between the input voltage and output voltage. There are 2 LEDs to indicate which voltage is measuring by the voltage meter. And it has a Power indicator LED (GREEN). You can change the input or output voltage measurement by Short press the button on the right side ,and also can close the voltage meter by pressing the button on the left side.

✍ USB output voltage is consistent with the output, not a fixed 5V output.
✍ When charging for digital equipment, make sure the USB output voltage is 5V.

Example:
Step down only
✅ 32V > 24V / 12V / 9V / 5V / 3.3V
✅ 24V > 12V / 9V / 5V / 3.3V
✅ 12V > 9V / 5V / 3.3V
✅ 5V > 3.3V

Unable to step up
❌ 5V > 9V / 12V / 24V / 30V
❌ 12V > 24V / 30V

▼ Features:
1. High power, high efficiency, 5A , low ripple;

2. Three in one:
( 1 ) Use as an ordinary step-down module with overcurrent protection capability;
( 2 ) Used as a charger for various voltage values ​​of lithium batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery pack), used in solar panels, wind generators, and other occasions;
( 3 ) Use as a high-power LED constant current drive module;

3. It has two modes of constant voltage and constant current, and there are indicators to indicate which mode the module is currently in;

4. When used as a lithium battery charger, the float voltage and charging current can be set, with indicator lights indicating, shows whether it is charging or fully charged;

5. With the current limiting protection function, the module will not be burnt out even if the output is short-circuited.
