The Genuino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 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 is compatible with most shields designed for the Uno, Duemilanove or Diecimila.
Genuino Mega and Arduino Mega share the same components, characteristics and quality of manufacturing. They are actually the same board under a different brand. Depending on the area of the world where you live you’ll be able to purchase an Arduino Mega or a Genuino Mega. Learn more.
Additional features coming with the R3 version are:
- ATmega16U2 instead 8U2 as USB-to-Serial converter
- 1.0 pinout: added SDA and SCL pins for TWI communication placed near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board and the second one is a not connected pin, that is reserved for future purposes
- stronger RESET circuit
