There’s a surprising lack of SitCore dev platforms with Ethernet. Would love to see a Pi form factor FEZ with Ethernet and possibly WiFi onboard!
Consider a board with a Click connector. A Click Ethernet board works great with SitCore.
260D dev has Ethernet
260Dev work great with either included
either external click ethernet ETH click - Breakout board for ENC28J60 Ethernet controller
even you have wifi module too WiFi 7 Click Board - MikroElektronika that you can use too
and work great with all those
