Arduino Ethernet Microcontroller is 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 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.
The board can also be powered via an external power supply. External power can come either from an AC-to-DC adapter (wall-wart) or battery. Each of the 14 digital pins on the Ethernet board can be used as an input or output. The Arduino Ethernet has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers.
