The XL4015 Step Down Module is a powerful 5A DC-DC buck converter that features a built-in LED voltmeter. It allows you to efficiently step down input voltages (up to 36V) to a precise lower output while monitoring the voltage levels in real-time.
How to use the button: The small button on the board switches the display between Input Voltage and Output Voltage. A generic LED usually lights up to indicate which one you are currently viewing.
Although rated for 5A, we recommend adding a small heatsink if you plan to run it above 3A for long periods to prevent overheating.

Core Functionality and Specifications

The module is based on the XL4015 integrated circuit, a powerful and efficient switching regulator.

Key Specifications

Feature	Specification
Main IC	XL4015 Buck Converter
Input Voltage $\mathbf{V_{IN}}$	$\mathbf{4\text{V}}$ to $\mathbf{38\text{V}}$ DC
Output Voltage $\mathbf{V_{OUT}}$	$\mathbf{1.25\text{V}}$ to $\mathbf{36\text{V}}$ DC (Adjustable)
Max Output Current	$\mathbf{5\text{A}}$ (Rated), $\mathbf{4.5\text{A}}$ Continuous (Cooling recommended above $3\text{A}$
Max Output Power	$\mathbf{75\text{W}}$
Conversion Efficiency	Up to $96\%$
Switching Frequency	$180\text{ kHz}$
Adjustment	Multi-turn Trimming Potentiometer (Pot)

Important Consideration: Step-down Requirement

As a step-down (buck) converter, the module requires the Input Voltage ( $\mathbf{V_{IN}}$ ) to be at least $1.5\text{V}$ to $2\text{V}$ higher than the Output Voltage ( $\mathbf{V_{OUT}}$ ) for proper regulation.

Digital Voltmeter Feature

The integrated 3-bit digital display is a major convenience feature of this specific module variant.

Display Type: $0.56$ -inch 3-digit LED display (typically red or blue).
Measurement: Displays the DC voltage.
Mode Button: A small tactile button allows the user to switch the display between showing the Input Voltage ( $\mathbf{V_{IN}}$ ) and the Output Voltage ( $\mathbf{V_{OUT}}$ ). This is invaluable for monitoring both source and load conditions without needing an external multimeter.
Calibration: Some versions include a calibration feature accessible via the button to ensure accuracy.

Module Pinout and Connections

The module has four main terminal points, usually screw terminals for secure wiring.

Terminal	Name	Function	Connection
$\text{IN+}$	Input Positive	Connects to the positive pole of the Power Source.	(e.g., $12\text{V}$ battery)
$\text{IN-}$	Input Negative	Connects to the negative pole of the Power Source (Ground).	(e.g., Battery Ground)
$\text{OUT+}$	Output Positive	Connects to the positive pole of the Load.	(e.g., $5\text{V}$ microcontroller circuit)
$\text{OUT-}$	Output Negative	Connects to the negative pole of the Load (Ground).	(e.g., Load Ground)

Adjustment

The output voltage is adjusted using the multi-turn trimming potentiometer (often blue/white) mounted on the board. Turning the pot allows you to precisely set the desired V_OUT.

Applications

The XL4015 module is versatile and suitable for many applications:

Bench Power Supply: Used to create a basic, variable voltage lab power supply from a fixed high-voltage adapter.
Battery Charging: Can be used as a constant current/constant voltage (CC/CV) charger for lithium batteries (requires a specific variant with separate current and voltage pots).
LED Drivers: Powering high-power LED strips or arrays.
Microcontroller Power: Efficiently stepping down a $12\text{V}$ or $24\text{V}$ source to a stable $5\text{V}$ or $3.3\text{V}$ for embedded electronics.
Solar Regulation: Used in small solar systems to step down panel voltage to charge a battery.
