43Requirements
44************
45
46This shield can only be used with a board that provides a configuration
47for Arduino connectors and defines node aliases for SPI and GPIO interfaces
48(see :ref:`shields` for more details).

50Programming
51***********
52
53Set ``--shield seeed_w5500`` when you invoke ``west build``. For example:
54
55.. zephyr-app-commands::
56   :zephyr-app: samples/net/dhcpv4_client
57   :board: nrf52840dk/nrf52840
58   :shield: seeed_w5500
59   :goals: build
