How to Use Mini AC-DC 110V-230V to 5V 700mA Module: Examples, Pinouts, and Specs

The Mini AC-DC 110V-230V to 5V 700mA Module by PermanentFly is a compact and efficient power supply module designed to convert high AC voltage (110V-230V) into a stable 5V DC output. With a maximum current output of 700mA, this module is ideal for powering low-voltage electronic devices, such as microcontrollers, sensors, and small IoT devices. Its small size and high efficiency make it a popular choice for embedded systems and DIY electronics projects.

• Powering microcontrollers (e.g., Arduino, ESP8266, ESP32, Raspberry Pi Pico)
• IoT devices and smart home applications
• Low-power sensors and modules
• DIY electronics and prototyping
• Replacing bulky linear power supplies in compact designs

1. Safety First: Ensure the module is handled with care, as it operates with high AC voltage. Always disconnect power before making any connections.
2. Connect AC Input:
   • Connect the AC IN1 pin to the live wire of the AC mains.
   • Connect the AC IN2 pin to the neutral wire of the AC mains.
   • Use proper insulation and secure connections to avoid electrical hazards.
3. Connect DC Output:
   • Connect the DC OUT+ pin to the positive terminal of your load (e.g., microcontroller VCC).
   • Connect the DC OUT- pin to the ground terminal of your load (e.g., microcontroller GND).
4. Verify Connections: Double-check all connections before powering the module.
5. Power On: Once all connections are secure, power on the AC mains. The module will provide a stable 5V DC output.

• Isolation: Ensure proper isolation between the AC and DC sides to prevent electrical shocks.
• Load Requirements: Do not exceed the maximum output current of 700mA to avoid overheating or damage.
• Heat Dissipation: If the module operates near its maximum load, ensure adequate ventilation to dissipate heat.
• Testing: Use a multimeter to verify the output voltage before connecting sensitive devices.
• Arduino Compatibility: This module can directly power an Arduino UNO or similar boards via their 5V and GND pins.

Below is an example of how to connect the module to an Arduino UNO and blink an LED:

• Connect DC OUT+ to the Arduino's 5V pin.
• Connect DC OUT- to the Arduino's GND pin.
• Connect an LED to pin 13 of the Arduino with a 220-ohm resistor in series.

// Simple LED Blink Example
// This code blinks an LED connected to pin 13 of the Arduino UNO.

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
}

1. Can this module power a Raspberry Pi?
   No, the module's maximum current output (700mA) is insufficient for most Raspberry Pi models, which typically require at least 2.5A.

2. Is the module safe to use with AC mains?
   Yes, but proper insulation and secure connections are essential to ensure safety.

3. Can I use this module outdoors?
   The module is not weatherproof. Use it only in dry, indoor environments or enclose it in a weatherproof case.

4. What happens if I exceed the maximum load?
   Exceeding 700mA may cause the module to overheat, shut down, or become permanently damaged.

This concludes the documentation for the Mini AC-DC 110V-230V to 5V 700mA Module by PermanentFly. Always prioritize safety and follow best practices when working with high-voltage components.
