I/O Expander and multiplexer

You need to connect your arduino to the internet, but you don't want to use ESP boards and you reject slow communication over Wi-Fi? Simply connect the arduino via an ethernet adapter - you can find those here.

You can also try the PoE (Power over Ethernet) mode that you add to some of these modules. It works by powering the modules and boards with a LAN data cable.
