Jetson boards from NVIDIA use MIPI CSI-2 camera connectors, but the pin layout differs between models such as the Jetson Nano, Xavier NX, and Orin series. Accurate pin identification is essential when connecting image sensors or camera modules. This article outlines the key differences in pinouts, highlights common connector types, and discusses the importance of using the correct adapters and documentation to avoid setup issues.
Introduction
NVIDIA Jetson camera pinout platforms are widely adopted for embedded systems and vision-based projects. One of the key features of these boards is their support for MIPI CSI-2 cameras. However, each Jetson board uses a different connector and pin layout, making it necessary to understand how the camera pinout is arranged before connecting any hardware.
Connector Types on Jetson Boards
Jetson boards generally use either a 15-pin or a 22-pin MIPI CSI-2 connector. For example, the Jetson Nano Developer Kit uses a 15-pin interface, while the Jetson Xavier NX and Orin series typically use a 22-pin connector. These connectors carry data, clock, power, and control signals for camera modules.
Jetson Nano 15-Pin Layout
The 15-pin port found on the Jetson Nano looks similar to Raspberry Pi camera connectors but has a different pin configuration. It supports two MIPI CSI-2 lanes along with I2C for camera control, power pins, and ground. Double-checking the voltage and signal types before connection is important to avoid any hardware damage.
Jetson Xavier NX and Orin 22-Pin Layout
The 22-pin layout is designed to support higher data throughput, often allowing for multiple camera lanes or simultaneous image streams. These connectors include multiple CSI lanes, clock signals, I2C, and additional GPIOs, which can be used for tasks such as triggering or sensor control.
Role of Adapter Boards
To connect cameras that don’t natively match Jetson pinouts, adapter boards are often necessary. These adapters map signals correctly between the camera and the Jetson board. Using the right adapter minimizes wiring errors and helps ensure a stable connection for both data and power.
Why Correct Pinout Matters
Incorrect wiring or pin mismatches can result in failed camera detection, image noise, or even permanent hardware faults. For this reason, it's important to refer to technical datasheets and verified schematics when working on camera integration. Taking the time to verify the connection can prevent costly mistakes.
Conclusion
Working with NVIDIA Jetson camera pinout interfaces requires attention to connector type and pin layout. Whether you’re using a 15-pin or a 22-pin setup, proper pin mapping and the right adapter board make the process safer and more reliable. Following technical documentation closely helps reduce errors during development.
