The Arduino Portenta Max Carrier is designed to assist developers with their prototypes by exposing the main peripherals of the high-density connectors of the Portenta family boards (H7 and X8). It allows for easy debugging through the JTAG connector and for inspection of the CAN lines through the pins. At the same time, it is the right tool to test Ethernet connectivity as well as to extend connectivity options (CAT-M1, NB-IoT and LoRa®).
