Requirements

This shield can only be used with a board which provides a configuration for Arduino connectors and defines node aliases for SPI and GPIO interfaces (see Shields for more details).

Note

This shield configuration limits the maximum SPI clock frequency to 2MHz although the TCAN4550-Q1 supports up to 18MHz SPI clock frequency. This is done to accommodate the flywires usually used for connecting the TCAN4550EVM to the board running Zephyr.
