3. Usage Instructions

How to Use the Hi-Link PM01 5V in a Circuit

1. Input Connection:

   • Connect the AC(L) pin to the live wire of the AC mains.
   • Connect the AC(N) pin to the neutral wire of the AC mains.
   • Ensure proper insulation and safety precautions when working with AC mains.

2. Output Connection:

   • Connect the +5V pin to the positive terminal of your load or circuit.
   • Connect the GND pin to the ground terminal of your load or circuit.

3. Mounting:

   • The module can be soldered onto a PCB or mounted using connectors.
   • Ensure adequate spacing between the AC and DC sides to prevent short circuits.

4. Safety Considerations:

   • Always use the module within its specified input voltage range (90V AC to 264V AC).
   • Avoid touching the module while it is powered to prevent electric shock.
   • Use a fuse or circuit breaker on the AC input for added protection.

Best Practices:

• Use a capacitor (e.g., 470µF) on the output to stabilize the voltage if your load is sensitive to fluctuations.
• Place the module in a well-ventilated area to prevent overheating.
• Avoid exposing the module to moisture or extreme temperatures.

4. Example Application with Arduino UNO

The Hi-Link PM01 5V can be used to power an Arduino UNO directly from an AC mains supply. Below is an example circuit and code to demonstrate its usage.

Circuit Diagram:

1. Connect the AC(L) and AC(N) pins of the PM01 to the AC mains (use proper insulation).
2. Connect the +5V pin of the PM01 to the 5V pin of the Arduino UNO.
3. Connect the GND pin of the PM01 to the GND pin of the Arduino UNO.

Arduino Code Example:

The following code blinks an LED connected to pin 13 of the Arduino UNO:

// Blink an LED connected to pin 13 of the Arduino UNO
// Ensure the Hi-Link PM01 5V is properly connected to power the Arduino

void setup() {
  pinMode(13, OUTPUT); // Set pin 13 as an output pin
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}
