The Arduino Ethernet is a microcontroller board based on the Arduino Uno, integrating the Ethernet controller WizNet W5100 TCP/IP. It is programmable like the Uno through a six-pin FTDI-type serial connector.

It includes a power-over-Ethernet (PoE) module to supply power through a conventional category 5 Ethernet cable. It is compatible with the IEEE802.3af standard and works with all compatible PoE injectors available.
