 <FeatureDescription>
-  The Portenta X8 is a high performance board, with many exceptional features. With two microprocessors combined, the NXP® i.MX 8M Mini MPU (Linux) and STM32H747XI dual Cortex®-M7+M4 32bit low power ARM® MCU (Arduino), this board is a great source to power the upcoming generation of Industrial Internet of Things.

+
+Thanks to the use of containers, the Portenta X8 offers an easy and secure way to deploy applications running in a controlled environment. The user has full control of the containers that the board is executing, having the option of creating and running custom containers on its own without the requirement of any additional subscription services and totally free of charge.  
+
+In case the user needs a more advanced and scalable professional solution, Arduino has created, in collaboration with Foundries, a subscription service with many enterprise-grade features:
+
+* Secure maintenance of Portenta X8 Linux distribution and applications over time
+* Portenta X8 fleets monitoring from anywhere
+* Secure Over-The-Air updates to target Portenta X8 devices/fleets

-    X8's integrated microcontroller is the dual core STM32H747 including a Cortex® M7 running at 480 MHz and a Cortex® M4 running at 240 MHz. The M4 core is available for real time control of motors and other time-critical machinery at a barebones level. The M7 core acts as a mediator between the peripherals and the i.MX 8M Mini and runs a proprietary firmware inaccessible to the User.
+    X8's integrated microcontroller is the dual-core STM32H747, including a Cortex® M7 running at 480 MHz and a Cortex® M4 running at 240 MHz. The M4 core can be programmed through the Arduino IDE to run sketches for multiple real-time applications, like control of motors or other time-critical machinery at a barebones level. The M7 core runs an Arduino custom firmware, normally invisible to the User, able to map all its peripherals as Linux devices.
