Raspberry Pi Camera Pinout Guide for Simple Camera Module Connections

Raspberry Pi camera pinout refers to the layout of pins used to connect camera modules to Raspberry Pi boards. This guide explains the pin configuration, how to identify the right connector, and what to keep in mind when connecting camera modules for various Pi models.

Connecting a camera to a Raspberry Pi can seem confusing at first, especially if you’re working with different board versions and camera types. The key is to understand how the camera interface is wired on your Raspberry Pi board.

What is a Camera Pinout?

A pinout is simply a diagram or reference showing which pins on a connector do what. For Raspberry Pi, the camera interface uses a MIPI CSI connector. This flat ribbon cable interface is used for high-speed connections between the camera and the board.

Raspberry Pi Camera Connector Types

Different Raspberry Pi models come with either a 15-pin or 22-pin camera connector:

• 15-pin CSI Connector: Commonly found on models like Raspberry Pi 4, 3, and earlier.

• 22-pin CSI Connector: Found on Raspberry Pi camera Zero and Raspberry Pi 5, this smaller connector works with smaller camera modules or requires an adapter to use standard 15-pin cameras.

Basic Pin Configuration (15-Pin)

Here is a simplified breakdown of the 15-pin connector used on most Raspberry Pi boards:

1. GND

2. CAM_D0_N

3. CAM_D0_P

4. GND

5. CAM_D1_N

6. CAM_D1_P

7. GND

8. CAM_CK_N

9. CAM_CK_P

10. GND

11. CAM_IO0

12. CAM_IO1

13. CAM_IO2

14. CAM_IO3

15. CAM_IO4

These connections help transmit the video data and control signals between the board and camera.

Connecting the Camera Module

To connect a camera module:

1. Shut down your Raspberry Pi.

2. Gently lift the CSI connector latch.

3. Insert the camera ribbon cable with the metal contacts facing the right direction (typically toward the HDMI port).

4. Push down the latch to lock the cable.

5. Power up your Raspberry Pi and test the connection using camera commands like libcamera-still or raspistill, depending on your setup.

Conclusion

Knowing the Raspberry Pi camera pinout helps in choosing the right module and connecting it properly to your board. Whether you're working on a simple photo capture project or building a smart camera setup, correct pin alignment and the right cable type are essential to get your project running smoothly.
