The Mega 2560 is an update for the Arduino Mega, which it replaces.
The board is a microcontroller board based on the ATmega2560-16AU .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.

This version is optimized in the original version to ensure consistent and compatible with the original, but also easy to use
Compatible with win7 and win8
This is a terminal adapter for the for arduino Nano.
It lables for arduino Nano version 3.0,
however you can still use this adapter for the older version
(just have to remember that A0-A7 are in the reverse order).
You can use this adapter to easily hook up for arduino Nano to an outside world via hook up wires.
