Description
MEGA 2560 Atmel R3 Board compatible with Arduino
The Arduino Mega 2560 R3 is an open-source precise Successor to the Arduino Mega based on the ATmega2560 SMD chip. The Mega 2560 R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allows the shields to adapt to the voltage provided from the board. The other is not connected and is reserved for future purposes. The Mega 2560 R3 works with all existing shields but can adapt to new shields which use these additional pins.
This Board 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. Using the board is also very easy, simply connect it to a computer with a USB cable or power it with a DC adapter or battery to get started. The Mega 2560 R3 board is designed for Arduino/Genuino Uno and the former boards Duemilanove or Diecimila.
