Arduino Mega 2560 R3 Board

The Arduino Mega 2560 R3 is  based on the ATmega2560.
It has 54 digital input/output pins (of which 15 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 2560 R3 board is compatible with most shields designed for Arduino/Genuino Uno and the former boards .
