Recommended operating voltage: 3.0V to 5.0V
Typical current consumption: 50mA (depending on the operating voltage)
Pin 2: GND (Ground)
Function: Provides a common ground connection for the laser module
Connect to the negative terminal of the power supply or GND of the microcontroller/regulated power source
Pin 3: Enable (EN)
Function: Enables or disables the laser module
Logic level: Active low (i.e., connecting EN to GND enables the laser, while connecting EN to VCC or leaving it floating disables the laser)
Recommended pull-up resistor: 1k to 10k (optional)
Pin 4: NC (No Connection)
Function: Not connected internally; can be left unconnected or used as a mechanical anchor for PCB mounting
Connection Structure:
To connect the SYD1230 laser module, follow these steps:

Overview

The SYD1230 is a compact, high-quality red point laser module emitting at 650nm with a power output of 5mW. This laser module is designed for precise and efficient operation in various applications, including robotics, IoT projects, and DIY designs.

Pinout and Connection

The SYD1230 laser module has a standard 3-pin layout:

| Pin | Description |
| --- | --- |
| VCC | Positive supply voltage (typically 3.3V or 5V) |
| GND | Ground connection |
| EN | Enable pin (active high, connects to a digital output from a microcontroller) |

Usage and Code Examples

### Example 1: Basic Laser Control using Arduino

This example demonstrates how to control the SYD1230 laser module using an Arduino board.

```cpp
const int laserEnablePin = 2;  // Choose a digital pin on your Arduino board

void setup() {
  pinMode(laserEnablePin, OUTPUT);
}

void loop() {
  // Turn the laser on for 1 second
  digitalWrite(laserEnablePin, HIGH);
  delay(1000);
  
  // Turn the laser off for 1 second
  digitalWrite(laserEnablePin, LOW);
  delay(1000);
}
```

In this example, the `laserEnablePin` is connected to the EN pin of the SYD1230 laser module. The Arduino board sends a digital signal to the enable pin to turn the laser on or off.

### Example 2: Laser Intensity Control using PWM with Raspberry Pi

This example shows how to control the intensity of the SYD1230 laser module using Pulse Width Modulation (PWM) on a Raspberry Pi.

```python
import RPi.GPIO as GPIO
import time

# Set up the GPIO library
GPIO.setmode(GPIO.BCM)

# Define the laser enable pin
laserEnablePin = 17

# Set up the laser enable pin as an output
GPIO.setup(laserEnablePin, GPIO.OUT)

# Set up PWM on the laser enable pin
pwm = GPIO.PWM(laserEnablePin, 100)  # 100 Hz frequency

try:
    while True:
        # Set the laser intensity to 50% (duty cycle)
        pwm.start(50)
        time.sleep(1)
        
        # Set the laser intensity to 100% (duty cycle)
        pwm.ChangeDutyCycle(100)
        time.sleep(1)
        
        # Set the laser intensity to 0% (duty cycle)
        pwm.ChangeDutyCycle(0)
        time.sleep(1)

except KeyboardInterrupt:
    # Clean up when the program is interrupted
    pwm.stop()
    GPIO.cleanup()
```

In this example, the `laserEnablePin` is connected to the EN pin of the SYD1230 laser module. The Raspberry Pi's GPIO library is used to set up PWM on the enable pin, allowing for adjustable laser intensity.
