This article provides a detailed guide on the camera pinout for NVIDIA Jetson boards, covering the 15-pin and 22-pin CSI connectors. It is a valuable resource for engineers and developers working with MIPI CSI-2 camera modules on platforms like Jetson Nano, Xavier NX, and Orin NX, ensuring correct camera connections for embedded vision tasks.
Introduction
NVIDIA Jetson camera pinout platforms are widely used for embedded vision applications, and integrating a camera is often the first step. To ensure proper functionality, it's essential to understand the pinout configurations for the camera connectors. This guide delves into the specifics of the 15-pin and 22-pin CSI connectors commonly found on Jetson boards, helping users accurately connect camera modules for their projects.
Jetson CSI Camera Interfaces Explained
NVIDIA Jetson boards use MIPI CSI-2 (Mobile Industry Processor Interface) for connecting camera modules. The two most common pinout configurations are:
15-pin connectors typically found on Jetson Nano and developer kits.
22-pin connectors used on more advanced platforms such as Jetson Xavier NX and Orin NX.
These connectors support high-speed image data transmission between the camera and the Jetson board. Understanding the layout of each pin is essential for proper camera integration.
Pinout for Jetson Nano 15-Pin Camera Connector
The 15-pin camera connector on the Jetson Nano provides basic functionality and is often used in simpler camera setups. Here's a look at the key pins:
MIPI CSI-2 Data Pins: Data0+, Data0-, Data1+, Data1-
Clock Pins: Clock+ and Clock-
Power Pins: 3.3V and GND
I2C Pins: SDA and SCL (used for camera control)
CAM_IO Pin: Typically used for reset or power-down functions
This layout supports basic single-lane camera connections and is compatible with common modules like the Raspberry Pi camera.
Jetson Xavier NX / Orin NX 22-Pin Camera Pinout
The 22-pin connector is found on higher-end Jetson models like the Xavier NX and Orin NX. This connector offers more flexibility for advanced applications, including dual camera setups or higher data throughput. Key pins include:
MIPI CSI-2 Data Pins: Two data lanes (Data0+, Data0-, Data1+, Data1-, Data2+, Data2-, Data3+, Data3-)
Clock Pins: Clock+ and Clock-
Power Pins: 1.8V, 3.3V, and Ground
I2C Pins: SDA and SCL for communication
GPIO Pins: For camera reset, trigger, or additional controls
With 4 data lanes and more control options, the 22-pin configuration enables robust, high-performance imaging systems.
Importance of Correct Pinout
Accurately wiring the camera to the Jetson board is crucial. Incorrect connections can lead to hardware failure or malfunction. Always refer to the official documentation or use trusted breakout boards when connecting the camera. A MIPI CSI-2 adapter or FPC breakout board can also help by clearly labeling each pin, making connections simpler and more reliable.
Common Applications for Jetson Camera Modules
High-speed Imaging: Connecting global shutter cameras for high-speed video capture.
Stereo Vision: Implementing dual camera setups for depth perception in robotics.
Industrial Vision: Integrating cameras in automated quality control systems.
Edge AI Applications: Using camera data for real-time edge processing with machine learning models.
In all these cases, correctly wiring the camera connector ensures reliable data flow, which is essential for the success of the project.
Conclusion
Knowing the correct camera pinout for NVIDIA Jetson camera pinoutboards is critical for the success of any embedded vision project. Whether using the 15-pin or 22-pin connectors, this guide helps users make the right connections, preventing hardware damage and ensuring accurate data transmission. Proper pinout knowledge is the first step toward building reliable and high-performance imaging systems with Jetson.
