Supported Hardware

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 constraints. Since memory usage in micro-ROS is a complex matter we provide a complete article describing it and a tutorial on how to tune the memory consuption 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.

The micro-ROS hardware support is divided into two categories:

Officially supported boards
Community supported boards

Officially supported boards

The officially supported boards are those which have been carried out or tested officially, and to which LTS is guaranteed.
