How to Use Led Module Green: Examples, Pinouts, and Specs

The Keyestudio LED Module Green (Part ID: KS0232) is a compact and efficient module featuring a green LED that emits bright green light when powered. It is designed for ease of use in a variety of electronic projects, making it ideal for beginners and professionals alike. This module is commonly used as an indicator, status light, or part of a display system in circuits. Its simple design allows for quick integration into breadboards, microcontroller projects, and other electronic systems.

• Power or status indicators in electronic devices
• Visual feedback in microcontroller projects
• Signal or warning lights in control systems
• Educational and prototyping purposes

The following table outlines the key technical details of the Keyestudio LED Module Green:

The module has a simple 3-pin interface, as described in the table below:

1. Power the Module: Connect the VCC pin to a 3.3V or 5V power source and the GND pin to the ground of your circuit.
2. Control the LED: Use the Signal (S) pin to control the LED. This pin can be connected to a microcontroller's GPIO pin or a simple switch. When the signal pin is HIGH, the LED will light up.
3. Resistor Consideration: The module includes an onboard current-limiting resistor, so no external resistor is required for typical use.

• Voltage Range: Ensure the input voltage does not exceed 5V to avoid damaging the module.
• Polarity: Double-check the connections to avoid reversing the polarity, which could damage the LED.
• Signal Control: When using a microcontroller, configure the GPIO pin as an output to control the LED.

Below is an example of how to connect and control the Keyestudio LED Module Green using an Arduino UNO:

• Connect the Signal (S) pin of the module to Arduino digital pin 8.
• Connect the VCC pin of the module to the Arduino's 5V pin.
• Connect the GND pin of the module to the Arduino's GND pin.

// Example code to control the Keyestudio LED Module Green (KS0232)

// Define the pin connected to the LED module
const int ledPin = 8;

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

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

• Use a breadboard for prototyping to ensure secure connections.
• Avoid prolonged operation at maximum current to extend the LED's lifespan.
• If using multiple LED modules, ensure the power supply can handle the total current draw.

1. LED Does Not Light Up

   • Cause: Incorrect wiring or reversed polarity.
   • Solution: Verify the connections and ensure the VCC and GND pins are correctly connected.

2. LED Flickers or Is Dim

   • Cause: Insufficient power supply or loose connections.
   • Solution: Check the power source and ensure all connections are secure.

3. Module Overheats

   • Cause: Excessive voltage or current.
   • Solution: Ensure the input voltage is within the 3.3V to 5V range.

Q: Can I use this module with a 3.3V microcontroller like the ESP32?
A: Yes, the module is compatible with 3.3V systems. Connect the VCC pin to the 3.3V output of your microcontroller.

Q: Do I need an external resistor for this module?
A: No, the module includes an onboard current-limiting resistor, so no additional resistor is required.

Q: Can I use PWM to control the brightness of the LED?
A: Yes, you can connect the Signal (S) pin to a PWM-capable GPIO pin on your microcontroller to adjust the LED brightness.

Q: Is the module waterproof?
A: No, the module is not waterproof. Avoid exposing it to moisture or liquids.
