The A000062 is an Arduino Due development board based on the AT91SAM3X8E ARM Cortex-M3 microcontroller. It is the first Arduino board based on a 32bit ARM core microcontroller. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analogue inputs, 4 UARTs (hardware serial ports), a 84MHz clock, an USB OTG capable connection, two DAC (digital to analogue), two TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button. The board contains everything needed to support the microcontroller, simply connect it to a computer with a micro USB cable or power it with a AC to DC adapter or battery to get started. The Due is compatible with all Arduino shields that work at 3.3V and are compliant with the 1.0 Arduino pinout. The Arduino Due can be powered via the USB connector or with an external power supply. The power source is selected automatically.
