Arduino Mega 2560 Microcontroller Rev3

Description User friendly USB programmable Arduino Microcontroller Open Source design based on the larger ATmega2560 54 digital I/O Pins and 16 analog I/O Pins 256 KB of Flash Memory, 8 KB of SRAM, and 4kB of EEPROM Clock Speed: 16 MHz The Arduino Mega 2560 Microcontroller Rev3 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 Arduino Mega is compatible with most shields designed for the Arduino Uno, Duemilanove, or Diecimila. The Arduino Mega can be powered via the 1.5m USB Cable Type A to B or with an external power supply. The Mega2560 differs from all preceding boar
