Arduino Mega 2560R3

The Arduino Mega 2560 R3, the successor to the Arduino Mega, is a microcontroller board based on a ATmega2560 AVR microcontroller. It has 70 digital input/output pins (of which 15 can be used as PWM outputs and 16 can be used as analog inputs), a 16 MHz resonator, a USB connection, a power jack, an in-circuit system programming (ICSP) header, and a reset button. The Arduino has an extensive support community, which makes it a very easy way to get started working with embedded electronics.
