Arduino introduces the Arduino Ethernet Microcontroller (No PoE) + USB2SERIAL Kit. A single board that integrates the ATMEGA328 Uno microcontroller with the ETH shield. To program the board you can use the included USB2SERIAL converter. The module can be bought separately - Arduino PoE Module (X000002) or you can choose the Arduino Ethernet board with PoE (A000051).
The Arduino Ethernet is a microcontroller board based on the ATmega328. It has 14 digital input/output pins, 6 analog inputs, a 16 MHz crystal oscillator, a RJ45 connection, a power jack, an ICSP header, and a reset button. An optional Power over Ethernet module can be added to the board as well. An onboard microSD card reader, which can be used to store files for serving over the network, is accessible through the SD Library. A six pin header can be connected to an FTDI cable or USB Serial board to provide USB power and communication to the board.
Power
The board can also be powered via an external power supply, an optional Power over Ethernet (PoE) module, or by using a FTDI cable/USB Serial connector. External power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack.
Input and Output
Each of the 14 digital pins on the Ethernet board can be used as an input or output. Each pin can provide/receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms.
Communication
The Arduino Ethernet has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. A SoftwareSerial library allows for serial communication on any of the Uno's digital pins. The ATmega328 also supports TWI and SPI communication.
