The 5V Adapter Board (Manufacturer Part ID: 5v_Adapter_Board) is a compact circuit board designed to convert AC mains voltage into a stable 5V DC output. This component is widely used to power low-voltage electronic devices, including microcontrollers, sensors, and other peripherals. Its small form factor and reliable performance make it an essential component in prototyping, DIY electronics, and embedded systems.








The following table outlines the key technical details of the 5V Adapter Board:
| Parameter | Value |
|---|---|
| Input Voltage | 100-240V AC (50/60Hz) |
| Output Voltage | 5V DC |
| Output Current | Up to 1A |
| Power Rating | 5W |
| Efficiency | ≥ 75% |
| Dimensions | Varies by manufacturer (e.g., 25mm x 20mm) |
| Operating Temperature | -20°C to +60°C |
| Safety Features | Over-voltage, over-current, and short-circuit protection |
The 5V Adapter Board typically has the following pin configuration:
| Pin Name | Description |
|---|---|
| AC IN (L) | Live wire input for AC mains voltage. |
| AC IN (N) | Neutral wire input for AC mains voltage. |
| GND | Ground connection for the DC output. |
| +5V | Positive 5V DC output. |
Note: Always verify the pin configuration on your specific board, as it may vary slightly depending on the manufacturer.
Connect the AC Input:
AC IN (L) and AC IN (N) pins on the board.Connect the DC Output:
+5V and GND pins to supply power to your circuit or device.Power On:
The 5V Adapter Board can be used to power an Arduino UNO. Follow these steps:
+5V pin of the adapter board to the 5V pin on the Arduino UNO.GND pin of the adapter board to the GND pin on the Arduino UNO.Here is a simple Arduino sketch to blink an LED while powered by the 5V Adapter Board:
// This sketch blinks an LED connected to pin 13 of the Arduino UNO.
// Ensure the Arduino is powered by the 5V Adapter Board.
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
}
Warning: Always double-check the connections before powering the circuit to avoid damage to the Arduino or other components.
| Issue | Possible Cause | Solution |
|---|---|---|
| No output voltage | Incorrect AC input connection | Verify the AC IN (L) and AC IN (N) connections. |
| Output voltage is unstable | Overloading the board | Ensure the connected load does not exceed 1A. |
| Board overheats | Insufficient ventilation or overloading | Provide proper ventilation and reduce the load. |
| Device connected to the board is not working | Incorrect polarity or loose connections | Check the +5V and GND connections for proper polarity and secure wiring. |
