Ethernet modules
The modules in this category will be useful when you want to connect your electronic projects to the Internet, whether for data collection, remote control of devices or smart home applications. Ethernet adapters are a great option if you don't want to use ESP boards and you're dismissing slow Wi-Fi communication out of hand. 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.

Arduino Ethernet module
Arduino Ethernet module , as the name suggests, will enable your Arduino board communicate over an Ethernet network. This opens the door to endless possibilities. For example, you can create projects that get data from the Internet (such as weather or other online sources) and use it to control sensors , motors or LEDs .
One of the main advantages of the Arduino Ethernet module is its relative ease of use. You can create a home automation system where you control lights, thermostat or even garden watering via the internet. Or how about creating your own weather station that collects and publishes data online?
