Arduino Mega 2560 Rev. 3 Microcontroller Board
Arduino Mega 2560 Rev. 3 Microcontroller Board is based on the Atmel ATmega2560 8-bit microcontroller (MCU). Arduino Mega 2560 features 54 digital input/output pins (15 of which can be used as PWM outputs) and 16 analog inputs. This MCU board also includes 4 UARTs (hardware serial ports), a 16MHz crystal oscillator, a USB connection, a power jack, an In-Circuit Serial Programming (ICSP) header, and a reset button. Arduino Mega 2560 includes everything the user needs to support the MCU. The user can get started by connecting the Mega 2560 to a computer with the USB cable or by powering it with an AC-DC adapter or battery. Arduino Mega 2560 board is compatible with most shields designed for the Uno and former boards Duemilanove or Diecimila. Mega 2560 is an update to the earlier Arduino Mega board.
