 micro-ROS also offers some other ways to crosscompile it for different platforms. These other options are secondary tools and may not have full support for all features. Currently micro-ROS is also available as:
 
+- a standalone **[micro-ROS component for Renesas e<sup>2</sup> studio and RA6M5](https://github.com/micro-ROS/micro_ros_renesas2estudio_component)**: this package enables the integration of micro-ROS in Renesas e<sup>2</sup> studio and RA6M5 MCU family.
 - a standalone **[micro-ROS component for ESP-IDF](https://github.com/micro-ROS/micro_ros_espidf_component)**: this package enables the integration of micro-ROS in any Espressif ESP32 IDF project.
 - a standalone **[micro-ROS module for Zephyr RTOS](https://github.com/micro-ROS/micro_ros_zephyr_module)**: this package enables the integration of micro-ROS in any Zephyr RTOS workspace.
