4 Communication Capabilities

The communication modules are some of the most important aspects of an SBC – the communication needed guides the type of SBC chosen for any specific application. The TCAN28XX line of devices do not disappoint as within the family there is support for classic CAN, CAN-FD, CAN-SIC, and LIN with devices varying depending on direct system needs.
