This is an Arduino Due with a Micro USB cable. It is the first ARM-based Arduino development board. This micro-controller board is based on the Atmel SAM3X8E ARM Cortex M3 CPU. It is the first Arduino board based on a 32-bit ARM core microcontroller. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), an 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button. There are also some cool features like DACs, Audio, DMA, an experimental multi-task library, and more.
