Requirements
************

This shield/breakout board can be used with any board with SPI interfaces in
Arduino header or custom header (by adjusting the overlay).

Programming
***********

Set ``-DSHIELD=arceli_eth_w5500`` when you invoke ``west build``. For example:

.. zephyr-app-commands::
   :zephyr-app: samples/net/dhcp_client
   :board: nrf52840dk_nrf52840
   :shield: arceli_eth_w5500
   :goals: build
