This is a retired product, but fear not as there is a newer, better version available: DEV-11061
Replacement: DEV-11061. This has been replaced with the new Arduino Mega 2560 R3. This page is for reference only.
Description: Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).
This is the original Arduino Mega. It's awesome, but it's recently been upgraded to the Arduino Mega2560. We will continue to sell the original (at a discount!), but once it sells out, you should jump over to the new version.
The Arduino Mega is a microcontroller board based on the ATmega1280. 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.

Note: This is the old-school Arduino Mega with the ATmega1280 uC. It's been replaced by the Mega 2560 R3 but we have a few of these left in stock so we're selling them at a reduced price. Once they're gone, they're gone for good so get them while you can!
