Arduino Due

The Arduino Due is the first Arduino with an ARM-based microcontroller. It is based on the Atmel SAM3X8E ARM Cortex-M3 CPU that enables a higher level of performance compared to Arduinos with 8-bit microcontrollers. The Arduino Due has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), a 84 MHz clock, a USB OTG capable connection, 2 DAC (digital to analog converters), 2 TWI, a power jack, an SPI header, a JTAG header, and reset and erase buttons.
