Arduino Ethernet

Overview

The Arduino Ethernet is a microcontroller board based on the ATmega328 datasheet . 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.

NB Pins 10, 11, 12 and 13 are reserved for interfacing with the Ethernet module and should not
be used otherwise. This reduces the number of available pins to 9, with 4 available as PWM outputs.

An optional Power over Ethernet module can be added to the board as well. The Ethernet differs from other boards in that it does not have an onboard USB-to-serial driver chip, but has a Wiznet Ethernet interface. This is the same interface found on the Ethernet
shield.

An onboard microSD card reader, which can be used to store files for serving over the network, is accessible through the SD Library. Pin 10 is reserved for the Wiznet interface, SS for the SD
card is on Pin

The 6-pin serial programming header is compatible with the USB Serial adapter and also with
the FTDI USB cables or with Sparkfun and Adafruit FTDI-style basic USB-to-serial breakout boards. It features support for automatic reset, allowing sketches to be uploaded without pressing the reset button on the board. When plugged into a USB to Serial adapter, the Arduino

Ethernet is powered from the adapter.
