PHYTEC link board ETH #####################

Overview

The link board ETH is an ethernet expansion board based on ENC424J600 ethernet controller and compatible with the Arduino UNO R3 connector. It was developed as an expansion component for the reel board. See :zephyr:board:reel_board documentation for more information about link board family and how to connect it to the reel board.
