Due Microcontroller Board

The Arduino Due is based on the Atmel SAM3X8E ARM Cortex-M3 CPU with 54 digital input/output pins, and 12 analog inputs. The Due has 54 digital input/output pins, of which 12 can be used as PWM outputs. The Due also has 12 analog inputs, 4 UARTs (hardware serial ports), a 84MHz clock, an USB OTG capable connection, 2 DAC (Digital-to-Analog Converters), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button, and an erase button.
