Pin Configuration

Raspberry Pi Camera Module 3 Pinout Explanation
The Raspberry Pi Camera Module 3 is a high-quality camera module designed specifically for Raspberry Pi boards. It features a 12-megapixel Sony IMX708 sensor, improved low-light performance, and supports 4K video recording at 30fps. The camera module has a 15-pin interface, which connects to the Raspberry Pi board's Camera Serial Interface (CSI) connector. Here's a detailed explanation of each pin:
Pinout Structure:
The 15-pin camera module connector has three rows of pins, with five pins in each row. The pinout structure is as follows:
Row 1: Pins 1-5 (top row)
Row 2: Pins 6-10 (middle row)
Row 3: Pins 11-15 (bottom row)
Pin-by-Pin Explanation:
Here's a detailed explanation of each pin:
Row 1: Pins 1-5 (Top Row)
1. Lane 0 (D0): This pin is used for data transmission. It carries the CSI-2 data signal from the camera module to the Raspberry Pi board.
2. Lane 1 (D1): This pin is used for data transmission. It carries the CSI-2 data signal from the camera module to the Raspberry Pi board.
3. PCLK (Pixel Clock): This pin provides the clock signal to the camera module, which is used to synchronize the data transmission.
4. VSYNC (Vertical Sync): This pin provides the vertical synchronization signal, which indicates the start of a new frame.
5. HSYNC (Horizontal Sync): This pin provides the horizontal synchronization signal, which is used to synchronize the data transmission within a frame.
Row 2: Pins 6-10 (Middle Row)
6. Reset (RST): This pin is used to reset the camera module.
7. PWRDN (Power Down): This pin is used to power down the camera module when not in use.
8. XCLK (External Clock): This pin is used to provide an external clock signal to the camera module.
9. Lane 2 (D2): This pin is used for data transmission. It carries the CSI-2 data signal from the camera module to the Raspberry Pi board.
10. Lane 3 (D3): This pin is used for data transmission. It carries the CSI-2 data signal from the camera module to the Raspberry Pi board.
Row 3: Pins 11-15 (Bottom Row)
11. Ground (GND): This pin provides a ground connection for the camera module.
12. VCC (Power Supply): This pin provides power to the camera module.
13. I2C SCL (Clock Signal): This pin is used for I2C communication, which is used to control the camera module's settings.
14. I2C SDA (Data Signal): This pin is used for I2C communication, which is used to control the camera module's settings.
15. Shield: This pin is a shield pin, which is connected to the ground internally. It helps to reduce electromagnetic interference (EMI).
Connecting the Pins:
To connect the Raspberry Pi Camera Module 3 to a Raspberry Pi board, follow these steps:
1. Align the camera module's 15-pin connector with the CSI connector on the Raspberry Pi board.
2. Gently push the camera module's connector into the CSI connector on the Raspberry Pi board until it clicks into place.
3. Make sure the camera module is securely connected and the pins are aligned properly.
Important Notes:
When handling the camera module, avoid touching the pins or the electrical components to prevent damage from static electricity.
Make sure to handle the Raspberry Pi board and camera module by the edges to prevent damage to the electrical components.
The camera module is sensitive to light, so it's recommended to keep it away from direct sunlight or intense light sources during assembly and storage.

 Pixel size: 1.4m x 1.4m
 Image resolution: Up to 4056 x 3040 pixels
 Video resolution: Up to 1080p at 30fps
 Interface: 15-pin MIPI CSI-2
 Connectivity: Compatible with Raspberry Pi boards (40-pin GPIO header)

Getting Started

To use the Raspberry Pi Camera Module 3, you'll need:

1. A Raspberry Pi board (compatible models: Raspberry Pi 4, Raspberry Pi 3, Raspberry Pi 2)
2. The Raspberry Pi Camera Module 3
3. A compatible power source
4. A microSD card with Raspbian OS (or other compatible operating system)

Code Examples

### Example 1: Capture a Still Image using Python

This example demonstrates how to capture a still image using the `picamera` library in Python.
```python
import picamera

# Create a camera object
camera = picamera.PiCamera()

# Set the camera resolution and orientation
camera.resolution = (1024, 768)
camera.rotation = 0

# Capture an image and save it to a file
camera.capture('image.jpg')

# Close the camera object
camera.close()
```
### Example 2: Record a Video using Python

This example shows how to record a video using the `picamera` library in Python.
```python
import picamera

# Create a camera object
camera = picamera.PiCamera()

# Set the camera resolution, orientation, and video stabilization
camera.resolution = (640, 480)
camera.rotation = 0
camera.video_stabilization = True

# Record a video and save it to a file
camera.start_recording('video.h264')
camera.wait_recording(10)  # Record for 10 seconds
camera.stop_recording()

# Close the camera object
camera.close()
```
### Example 3: Stream Live Video using Flask and Python

This example demonstrates how to stream live video from the camera module using Flask and Python.
```python
from flask import Flask, Response
import picamera
import io

app = Flask(__name__)

# Create a camera object
camera = picamera.PiCamera()

# Set the camera resolution and orientation
camera.resolution = (640, 480)
camera.rotation = 0

@app.route('/video_feed')
def video_feed():
    return Response(gen(camera), mimetype='multipart/x-mixed-replace; boundary=frame')

def gen(camera):
    while True:
        img = camera.capture_bytes('jpg', use_video_port=True)
        yield (b'--frame
'
               b'Content-Type: image/jpeg

' + img + b'
')

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000, debug=True)
```
In this example, a Flask web server is created to stream the live video feed from the camera module. The `video_feed` function captures JPEG images from the camera and yields them as a response to the client.
