Arduino MKR ETH Shield

Arduino MKR ETH Shield enables an MKR board to connect to the internet using the Ethernet 2 Library and to read and write to a microSD card using the SD Library. The MKR ETH Shield is based on the WIZnet W5500 Embedded Ethernet Controller, which provides a network (IP) stack capable of both TCP and UDP. It supports up to eight simultaneous socket connections.

The W5500 and microSD card share the SPI bus. Only one at a time can be active. If using both peripherals in the program, this should be taken care of by the corresponding libraries. If not using one of the peripherals in the program, explicitly deselect it.

Features
