Raspberry Pi Camera Pinout: A Complete Guide to Connecting Your Camera Modules

Introduction
The Raspberry Pi has revolutionized the way we approach DIY projects, particularly with camera modules. Whether you're using the Raspberry Pi for a smart security system, robotics, or a simple camera project, understanding the camera pinout is crucial for successful integration. The Raspberry Pi camera pinout refers to the specific wiring that connects your camera module to the Raspberry Pi board. With a bit of knowledge, you can set up your camera quickly and avoid common connection issues.

Understanding the Camera Pinouts
Raspberry Pi boards feature two main types of camera connectors: the 15-pin and 22-pin connectors. The type of connector used depends on your Raspberry Pi model. The 15-pin connector is common on earlier models like Raspberry Pi 4, while the 22-pin connector is used in Raspberry Pi 5 and newer models. The pinout determines how the camera module communicates with the board, ensuring everything from power supply to data transfer functions properly.

15-Pin Camera Connector (For Raspberry Pi 4 and Earlier Models)
For Raspberry Pi 4 and older versions, you'll commonly encounter the 15-pin camera connector, which is used for MIPI CSI-2 (Mobile Industry Processor Interface). This pinout offers the essential connections for power (1.8V and 3.3V), clock signals, image data lanes, and I2C lines for communication. Understanding this pinout is crucial for ensuring you correctly wire the camera module, preventing malfunctions.

22-Pin Camera Connector (For Raspberry Pi 5 and Newer Models)
The 22-pin connector, used in Raspberry pi camera and newer boards, offers more flexibility with additional data lanes (DATA2± and DATA3±), increasing the bandwidth. These extra lanes improve the performance of high-resolution video and make the connection ideal for advanced applications like live streaming, security surveillance, and machine vision. The 22-pin configuration also supports backward compatibility with the 15-pin modules, depending on the specific needs of your project.

Common Mistakes to Avoid
When working with Raspberry Pi camera pinouts, a few common mistakes can disrupt your setup. One of the most frequent issues is connecting the ribbon cable incorrectly. Always make sure that the metal contacts are facing the correct direction when connecting to the board. Another mistake to watch out for is using the wrong connector type. It’s important to verify which pinout your Raspberry Pi board uses before purchasing any camera modules or connectors. Lastly, make sure your connections are fully secure. Loose cables or partial insertions can result in unstable performance.

Why Choosing the Right Pinout Matters
The correct Raspberry Pi camera pinout is essential for achieving stable, high-quality video output. Whether you are building a robot, a surveillance camera system, or a home automation project, a proper connection ensures that your Raspberry Pi can communicate effectively with the camera module. Using the right pinout also ensures that your camera gets the right amount of power and that data is transferred at the correct speed, minimizing lag or glitches in your video feed.

Conclusion
Setting up a camera with your Raspberry Pi doesn't have to be complicated. By understanding the Raspberry Pi camera pinout and ensuring the correct wiring, you can create a robust camera system with minimal hassle. Whether you're using the 15-pin connector on a Raspberry Pi 4 or the 22-pin connector on a Raspberry Pi 5, proper integration will make your project come to life. Always double-check your pin connections, and don't forget to follow the specifications for your specific Raspberry Pi model to get the best performance. With the right setup, you'll be able to leverage the full potential of your Raspberry Pi camera module.

🐯 🚀 Timescale is now TigerData: Building the Modern PostgreSQL for the Analytical and Agentic Era

We’ve quietly evolved from a time-series database into the modern PostgreSQL for today’s and tomorrow’s computing, built for performance, scale, and the agentic future.

So we’re changing our name: from Timescale to TigerData. Not to change who we are, but to reflect who we’ve become. TigerData is bold, fast, and built to power the next era of software.
