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 :ref: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.
