ARDUINO MEGA 2560 R3 (ORIGINAL CHIP)

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. FlashProcessingMaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS XWindowsand Linux). The Arduino Mega 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 inputs4 UARTs (hardware serial ports)a 16 MHz crystal oscillatora USB connectiona power jackan ICSP headerand 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. The Mega 2560 R3 also adds SDA and SCL pins next
