The comment to use psocketbeagle and MK if Linux is required is good.
I just looked up psocketbeagle and I don't see any network interface.
 Likely if you want a Linux based controller it is so you can access
it remotely.     You might get a USB/Wifi dongle to work but it would
be better to buy a board with built-in networking if networking is
important.   But the pocket beagle could always use a serial line for
networking if all you need is a text window and a few file transfers.

If you don't need Linix then it can be much simpler (An Arduino would
work) but remote access is a very nice feature to have.  Nice enough
that I'd go with a card that has built in wifi.
