 # Description
-The Arduino® Portenta X8 is a high performance system on module designed to power the upcoming generation of Industrial Internet of Things. This board combines the NXP® i.MX 8M Mini hosting an embedded Linux OS with the STM32H7 to leverage Arduino libraries/skills. Shield and carrier boards are available to extend the functionality of the X8 or alternatively can be used as reference designs to develop your own custom solutions.

 The X8 includes an embedded H7 in the form of a STM32H747AII6 IC (U20) with a dual core ARM® Cortex® M7 and ARM® Cortex® M4. This IC is used as a I/O expander for the NXP® i.MX 8M Mini (U2). Peripherals are automatically controlled via the M7 core. Additionally, 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. The STM32H7 is not exposed to networking and should be programmed via the i.MX 8M Mini (U2). 
 
 ## Wi-Fi®/Bluetooth® Connectivity
-The Murata® LBEE5KL1DX-883 wireless module (U9) simultaneously provides Wi-Fi® and Bluetooth® connectivity in an ultra small package based on the Cypress CYW4343W. The IEEE802.11b/g/n Wi-Fi® interface can be operated as an access point (AP), station (STA) or as a dual mode simultaneous AP/STA and supports a maximum transfer rate of 65 Mbps. Bluetooth® interface supports Bluetooth® Classic and Bluetooth® Low Energy. An integrated antenna circuitry switch allows a single external antenna (J4 or ANT1) to be shared between Wi-Fi® and Bluetooth®. Module U9 interfaces with i.MX 8M Mini (U2) via a 4bit SDIO and UART interface. Based on the software stack of the wireless module in the embedded linux OS, Bluetooth® 5.1 is supported together with Wi-Fi® conforming to the IEEE802.11b/g/n standard.

 ## Onboard Memories
 The Arduino® Portenta X8 includes two onboard memory modules. A NT6AN512T32AV 2GB LP-DDR4 DRAM (U19) and 16GB Forsee eMMC Flash module (FEMDRW016G) (U5) are accessible to the i.MX 8M Mini (U2).
