# Introduction

OrbbecSDK ROS2 Wrapper provides seamless integration of Orbbec cameras with ROS 2 environment. It supports ROS2 Foxy, Humble, and Jazzy distributions.

By default, we recommend using the **v2-main** branch. For older OpenNI devices not supported by v2-main, please use the **main** branch. Device models that are only supported by the main branch are listed in the table below.

If you are a user in China, it is recommended to use [gitee Repo](https://gitee.com/orbbecdeveloper/OrbbecSDK_ROS2).

## Support Hardware Products

The following devices are supported by the OrbbecSDK ROS2 Wrapper v2-main branch.  More devices support will be added in the near future. If you can not find your device in the table below, try the [main](https://github.com/orbbec/OrbbecSDK_ROS2)  branch.

For optimal performance, we strongly recommend updating to the latest firmware version. This ensures that you benefit from the most recent enhancements and bug fixes.

All launch files are essentially similar, with the primary difference being the default values of the parameters set
for different models within the same series. Differences in USB standards, such as USB 2.0 versus USB 3.0, may require adjustments to these parameters. If you encounter a startup failure, please carefully review the specification manual. Pay special attention to the resolution settings in the launch file, as well as other parameters, to ensure compatibility and optimal performance.
