Description
The Arduino® Portenta X8 is a high-performance system on module designed to power the upcoming generation of the Industrial Internet of Things. This board combines the NXP® i.MX 8M Mini (4+1-cores) hosting an embedded Linux OS with the STM32H7 (2-cores) for real-time applications in the Arduino environment. Shield and carrier boards are available to extend the functionality of the Portenta X8 or alternatively can be used as reference designs to develop your own custom solutions.
