This project focuses on the use and application of the Hi-Link HLK-20M12, a compact and efficient Switch Mode Power Supply (SMPS) module. The module is designed to convert high-voltage AC input (90–264V AC) directly into a regulated 12V DC output with a maximum power rating of 20W (1.67A).

The HLK-20M12 is a highly integrated power module that offers high efficiency, low power consumption, and built-in overvoltage, overcurrent, and short-circuit protection, making it ideal for various embedded systems and electronic projects.

The purpose of using this module is to provide a stable 12V DC power supply for devices such as microcontrollers, sensors, IoT systems, LED drivers, and more, without the need for bulky transformers or complex circuitry. Its compact size, high efficiency, and safety features make it suitable for modern low-power electronic devices and industrial applications.
