ARDUINO ™ MEGA 2560
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 analogue 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.
