Hi kotchanon,
You can use Arduino MKR CAN shield which is based on MCP2515 controller with SPI Interface. This shield can be used to enable CAN connectivity on arduino platforms. This shield opens a new set of possible applications like smart vehicles, autonomous cars, industrial systems and drones.
In order to communicate with each other, make sure you install hardware support, update firmware, configure hardware connection, then prepare model for hardware connection and then run model on target hardware. For more information on how to do that process you can refer to this link. Simulink support package is functional from R2013a and beyond.
If you are using MATLAB R2020a.You can use Arduino Due, Arduino Uno, Arduino Leonardo, Arduino Mega 2560, Arduino Mega ADK boards along with shield supports as Boards.
If in case you are using older versions of MATLAB you can refer to this link for the type of Board and shield support to be used. Hope this Helps!
