<p>By default, we recommend using the <strong>v2-main</strong> branch. For older OpenNI devices not supported by v2-main, please use the <strong>main</strong> branch. Device models that are only supported by the main branch are listed in the table below.</p>
<p>If you are a user in China, it is recommended to use <aclass="reference external"href="https://gitee.com/orbbecdeveloper/OrbbecSDK_ROS2">gitee Repo</a>.</p>
<h2><spanclass="section-number">1.1.1. </span>Support Hardware Products<aclass="headerlink"href="#support-hardware-products"title="Link to this heading"></a></h2>
<p>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 <aclass="reference external"href="https://github.com/orbbec/OrbbecSDK_ROS2">main</a> branch.</p>
<p>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.</p>
<p>To learn how to obtain and upgrade the latest firmware, <aclass="reference internal"href="../3_quickstarts/orbbecviewer.html"><spanclass="doc">please click here</span></a>.</p>
</table><p>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.</p>
