 Micro-ROS aims to **bring ROS 2 to a wide set of microcontrollers** to allow having first-class ROS 2 entities in the embedded world.
 
-The main targets of micro-ROS are mid-range 32-bits microcontroller families. Usually, the minimum requirements for running micro-ROS in an embedded platform are memory constrains. Since memory usage in micro-ROS is a complex matter we provide a [complete article](https://micro-ros.github.io/docs/concepts/memo_prof/) describing it and a tutorial on [how to tune the memory consuption](https://micro-ros.github.io/docs/tutorials/core/microxrcedds_rmw_configuration/) in the micro-ROS middleware.

 In general micro-ROS will need MCUs that have tens of kilobytes of RAM memory and communication peripherals that enable the micro-ROS [Client to Agent communication](https://micro-ros.github.io//docs/overview/features/).

 - reference micro-ROS board, 
 - tier 2 boards and, 
 - community supported boards.

-Zephyr is a scalable open source Real-Time Operating System (RTOS) designed to fit resource constrained and embedded systems, with safety and security in mind. It forms part of [the Linux Foundation](https://www.linuxfoundation.org/), which supports a wide range of open source projects. Zephyr targets the same range of systems and applications with deterministic and time-critical constrains as micro-ROS, such as connected sensors and actuators, microcontrollers and small IoT devices of all kinds. micro-ROS and Zephyr complement each other by allowing to easily create heterogeneous distributed robotic systems and also integrate these devices seamlessly into the ROS 2 ecosystem.
