NVIDIA Jetson Camera Pinout: A Practical Guide for CSI Camera Integration
NVIDIA Jetson camera pinout plays a crucial role when connecting MIPI CSI-2 cameras to Jetson boards like Nano, Xavier NX, and Orin. This guide covers the key details of the pin configuration, connector types, and best practices to avoid connection issues during camera setup.
Introduction
Working with embedded systems like the NVIDIA Jetson series often involves adding camera modules for computer vision projects. These Jetson boards, including the Nano, Xavier NX, and Orin, rely on MIPI CSI-2 interfaces to communicate with cameras. To make these connections work properly, one must follow the camera pinout of each Jetson board accurately.
What Is a Camera Pinout?
A camera pinout refers to the arrangement of physical pins in the camera connector, each assigned with a specific function. In the case of Jetson boards, these functions include transmitting data, receiving clock signals, and supplying power to the camera module.
Jetson Board Connectors
NVIDIA Jetson camera boards typically use two types of CSI connectors:
15-pin connectors (commonly found on the Jetson Nano)
22-pin connectors (used in Jetson Xavier NX and Jetson Orin)
Each of these connectors has a different pin configuration. Using the wrong pinout reference can lead to incorrect wiring or even hardware damage.
Signal Types in the Pinout
The camera pinout includes several key signal lines:
CSI Data Lanes (Data0+, Data0-, Data1+, Data1-)
CSI Clock Lanes (CLK+, CLK-)
I2C Lines (SCL, SDA) for camera control
Power Supply (e.g., 3.3V, 5V)
Ground Pins (GND)
CAM_GPIO or Power Down Controls
Each line must be correctly aligned with the corresponding pin on the camera module's cable or board.
Importance of Proper Connection
Incorrect pin mapping may cause your camera not to work, or worse, cause permanent hardware issues. Before connecting any module, verify both the Jetson board's pinout and your camera’s connector. A mismatched connection could result in no image output or unstable signal behavior.
Using Adapter Boards
Some developers choose to use adapter boards that convert 15-pin to 22-pin interfaces or vice versa. These boards are helpful when switching between different camera types or using custom modules. Make sure these adapters are designed specifically for NVIDIA Jetson devices.
Conclusion
NVIDIA Jetson camera pinout is one of the most important technical aspects of camera integration. Whether you're setting up a prototype or building a production-ready system, following the correct pinout ensures proper communication between the Jetson board and your camera module. Always refer to official documentation or tested pinout charts before finalizing your setup.
