Both variants of the Arduino Pro 4G Module are designed for use with the Portenta family. To operate, these modules require a compatible carrier and a board from the Portenta family. The specific compatibilities are:
647
664
648
665
-**Arduino Portenta Mid Carrier**: Compatible with all boards from the Portenta family.
649
666
-**Arduino Portenta Max Carrier**: Only compatible with the Portenta X8 board.
