Arduino Ethernet is a microcontroller board based on the Arduino Uno and uses an integrated Wiznet W5100 TCP / IP Ethernet controller.
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.
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 4.
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.
The Arduino UNO Platinum is a microcontroller board based on the ATmega328. It has 14 digital inputs (6 of which can be used as PWM channels), 6 analog inputs, a 16 MHz Quartz, USB interface, a 6-pin ISP connector and a reset button. It contains everything needed to start and you can simply connect a USB cable to the PC or run via a power supply / battery.

The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.
Other features of the R3 version are: · ATmega16U2 8U2 instead of USB to serial converter · 1.0 pinout added SDA and SCL pins for TWI communication · A stronger reset circuit "
The Arduino Mega 2560 is a development board based on the ATmega2560 microcontroller. The Arduino Mega 2560 board is suitable for controlling numerous projects. Due to the simplicity of programming the Arduino Mega 2560 also ideal for beginners. The Arduino Mega 2560 board has 54 digital I / O's (of which 14 as PWM outputs can be used), 16 analog inputs, 4 UARTs (Serial Hardware Interfaces), 16 MHz crystal oscillator, USB interface, power supply, ICSP header, and a reset button. The Arduino Mega 2560 contains everything needed for use. Connect the Arduino Mega 2560 board easily via the included USB cable to a computer or fit the Arduino board via a feed stream. The Arduino Mega 2560 is compatible with most shields the Arduino Duemilanove or Diecimila to be developed. Though The Arduino Mega 2560 board requires a supply voltage of 5V, an external voltage source from 7-12V required. A suitable power supply for the Arduino Mega 2560 can be found in the accessories on this page. Additional benefits of the Arduino Mega 2560 R3 version are:
ATmega16U2 instead of the 8U2 USB-to-Serial converter
1.0 pinout: added SDA and SCL pins for TWI communication
