MikroElektronika Two Wire ETH Click
Overview
The Two-Wire ETH Click Shield is a compact add-on board featuring the LAN8651B1-E/LM [2], a low-power 10BASE-T1S MAC-PHY Ethernet Controller with SPI from Microchip. It combines a MAC and Ethernet PHY to provide low-cost MCUs access to 10BASE-T1S networks with support for multidrop and point-to-point topologies. Host communication uses high-speed SPI per the OPEN Alliance 10BASE-T1x MAC-PHY Serial Interface specification. More information at Two-Wire ETH Click Shield website [1].

Programming
Set --shield mikroe_two_wire_eth_click when you invoke west build. For example:
# From the root of the zephyr repository
west build -b frdm_mcxn947/mcxn947/cpu0 --shield mikroe_two_wire_eth_click samples/net/dhcpv4_client
