Arduino Mega 2560
Arduino Mega2560 microcontroller board is an easy-to-use development board based on the Atmel ATmega2560 MCU. The ATmega2560 has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of SRAM, and 4 KB of EEPROM. The Arduino Mega2560 microcontroller board 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. The Arduino Mega2560 contains everything needed to support the MCU. Simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. This Arduino development board is compatible with most shields designed for the Arduino Duemilanove or Diecimila. The Arduino Mega2560 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter. The Arduino MCU board includes a number of facilities for communicating with a computer, another Arduino, or other MCUs.
