Arduino Ethernet Rev3 development board

Ethernet Rev3, ATmega328, 14 Digital I/O Pins, 6 Analog Input Pins, 4 PWM Digital I/O Pins, 28g The Arduino Ethernet is a microcontroller board based on the Arduino Uno, and incorporating a WizNet W5100 TCP/IP Embedded Ethernet Controller. It can be programmed like an Uno via a six-pin FTDI -style serial connector. The Arduino USB-to-Serial adapter or any FTDI-style USB-to-serial connector can be used to program it.
A separate power-over-Ethernet (PoE) module can be soldered to the board to provide power from a conventional twisted pair Category 5 Ethernet cable. It is IEEE802.3af compliant, and works with all compliant PoE injectors currently available.
Compatible with PoE Module 12V (X000002).
