| 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. |
