 This demo illustrates the micro-ROS capabilities and showcases the integration of micro-ROS with ROS 2 tools. Besides, it enables the comparison of micro-ROS and ROS 2 outcomes.
 
-The use-case consists in a ROS2-controlled [Raspberry Pi 4](https://www.raspberrypi.org/products/raspberry-pi-4-model-b/?resellerType=home) with a [TFMini](https://www.sparkfun.com/products/14588) sensor that measures the <span style="color:magenta">distance</span> to a target object and a micro-ROS-controlled [Olimex STM32-E407](https://www.olimex.com/Products/ARM/ST/STM32-E407/open-source-hardware) board with the similar TFMini sensor, which measures the <span style="color:magenta"> distance</span> to the same object. The demo explores another micro-ROS-controlled Olimex STM32-E407 board, which measures the <span style="color:magenta">power consumption</span> of both Raspberry Pi 4 and Olimex STM32-E407 boards for distance measurements, using [INA219](https://www.antratek.com/ina-219-dc-current-sensor) sensors. The last component, a tablet display, visualizes measurement results using standard ROS 2 tools (rqt).

 Raspberry Pi 4 is running Linux and a ROS 2 application, while Olimex STM32-E407 boards are running NuttX and micro-ROS applications.Both of them are publishing sensor messages via UDP over  Ethernet LAN sending  distance and power data to the display. The tablet is running Linux, ROS 2 and a [micro-ROS agent](https://micro-ros.github.io/docs/overview/) to receive these messages.
