Raspberry Pi Camera Pinout Guide for Accurate CSI Camera Connection

Raspberry Pi camera pinout provides the layout of connections on the Camera Serial Interface (CSI) used to attach camera modules. Whether you're working with a 15-pin or 22-pin connector, knowing the pin assignment is critical for proper setup and reliable image transmission.

Introduction
The Raspberry Pi is a popular platform for camera-based applications such as surveillance systems, time-lapse photography, and vision-powered projects. Most models come with a Camera Serial Interface (CSI) connector designed for official Raspberry Pi cameras and compatible modules. Before connecting any camera, it’s important to know the pinout of the CSI connector to avoid connection errors.

Types of CSI Connectors
Raspberry Pi boards generally use two types of CSI connectors:

15-pin connector: Common on models like Raspberry Pi 4, 3, and Zero.

22-pin connector: Found on newer models like the Raspberry Pi 5, CM4 IO board, or when using certain adapter boards.

Pin Layout: 15-Pin Connector
The 15-pin CSI connector used on many Raspberry Pi models has a specific arrangement. From left to right (facing the connector with the locking tab on top), these include:

Ground

CAM_D0_N

CAM_D0_P

Ground

CAM_D1_N

CAM_D1_P

Ground

CAM_CLK_N

CAM_CLK_P

Ground

CAM_IO0

CAM_IO1

CAM_IO2

CAM_IO3

3.3V power supply

Pin Layout: 22-Pin Connector
The 22-pin connector supports additional features and is compatible with high-speed camera modules. Its pinout includes more control and data lines, allowing for advanced image capture functions. Boards like the Compute Module 4 or Raspberry Pi 5 use this interface to support multiple cameras or advanced camera stacks.

Use Cases
Knowing the pinout is not just technical trivia—it’s practical. Whether you're making a DIY camera project or integrating a module into a production system, miswiring can lead to damaged components or failed camera detection. Having a clear reference ensures correct connections during prototyping and development.

Conclusion
Raspberry Pi camera pinout information is a crucial part of any camera-based setup using CSI connectors. Before plugging in your camera module, make sure you’re matching the correct pin numbers and signal lines. This simple step can save time and protect your components from short circuits or miscommunication between devices.
