Here's a breakdown of its key features and functionalities:

5A CC CV Charging: This module supports Constant Current (CC) and Constant Voltage (CV) charging modes. In the CC mode, it provides a fixed current output, and in the CV mode, it maintains a constant voltage output. This is commonly used for charging lithium batteries, where the charging current and voltage need to be controlled to ensure safe and efficient charging.

LED Drive: It can be used to power and control LEDs. The ability to provide a consistent current and voltage is essential for driving LEDs, especially high-power LEDs or LED strips.

USB Voltmeter: The module is equipped with a USB voltmeter, which allows you to monitor the output voltage. This feature is helpful for checking the charging voltage or the voltage supplied to LEDs.

Adjustable Output: You can typically adjust the output voltage and current settings using potentiometers or trimmers on the module. This flexibility allows you to customize the module for different applications.

Protection Features: Many of these modules come with built-in protection features, such as overcurrent protection and over-temperature protection, to ensure safe operation and prevent damage to the module and connected devices.

Input and Output Terminals: The module has input terminals for the power source (e.g., DC input) and output terminals for connecting the load (e.g., lithium battery or LEDs).

Display: Some modules may have an LED display to show the current and voltage settings or battery charging status.
