Arduino A000067 Board Mega 2560 Core Atmel AVR

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 "
