HLK-PM01 Isolated Step Down AC-DC Power Module 220V to 5V

Description

What it is

The AC-DC HLK-PM01 power module is an isolated device that converts alternating current from 220V to a stable direct current voltage of 5V. This component is essential to ensure safe and reliable power supply for your electronic projects.

Features

• 220V AC to 5V DC power supply
• Isolated module to protect sensitive circuits

What it is for

Ideal for powering Arduino-based projects and other devices that require a 5V voltage. You can use it to power servos, sensors, and other low-power components.

Tutorial: How to use HLK-PM01

The HLK-PM01 module converts power from 220V AC to 5V DC, perfect for powering your Arduino projects and low-power devices.

What you need

• HLK-PM01
• AC-DC 220V cable
• Arduino or electronic circuit
• Protection resistor (optional)

Steps

1. 1. Check that the power supply is 220V AC.
2. 2. Connect the AC-DC cable to a household outlet.
3. 3. Connect the output of the module to a power pin of your Arduino.
