Arduino Mega 2560 R3 (genuine Arduino) A000067

Product information:

Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital I/O pins (14 of which can be used as PWM outputs), 16 analog inputs, 4 UARTs (serial hardware interfaces), a 16-MHz crystal oscillator, a USB interface, a power connection, an ICSP header and a reset button. It contains everything you need to accompany the microcontroller. Simply connect the board to a computer via USB or run it on an AC/DC adapter or battery to get started. Arduino Mega is compatible with the majority of shields designed for Arduino Due, Duemilanove or Diecimila.

Other features of the R3 version are:

- ATmega16U2 instead of the 8U2 USB to serial converter
-A stronger RESET circuit
- 1.0 pinout: added SDA and SCL pins for TWI communication near the AREF pin and two more new pins near the RESET pin — the IOREF pin, which allows the shields to adapt to the voltage supplied by the board, and a second pin that is not connected but is reserved for future use.
