The Arduino Due is a development board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board based on a 32-bit ARM cortex microcontroller. It has 54 digital input/output pins (12 of which can be used as PWM outputs), 12 analog inputs, 4 UART modules (hardware serial ports), an 84 MHz clock, a USB OTG capable connection, 2 DACs (digital to analog converters), 2 TWI/I2C modules, a power jack, an SPI header, a JTAG header, a reset button and an erase button.
