Replacing the Ardunio Mega, this board has the most ports of any Arduino board. Having a 54 digital input/output pins with 15 as PWM along with 16 analog inputs and 4 UARTs there are more than enough for most crazy projects. Like the Uno, it can also be powered from either the USB cable provided, or from a wall socket or 9V battery using the DC power jack.
The board layout is design to allow most shields for the Uno and Duemilanove boards.
As for all Arduino-related microcontroller products, we recommend you download both the FTDI and CH340 drivers before using Arduino.
