The Due board for Arduino is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board based on a 32-bit ARM core microcontroller.
nIt has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analogue inputs,
n4 UARTs (hardware serial ports), an 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analogue), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button.
nOperating voltage: 3.3V
nInput voltage(recommended): 7V – 12V
nInput Voltage (limits): 6-16V
nDigital I / O pins: 54(of which 12 provide PWM output)
nAnalog input pins: 12
nAnalogue outputs pins: 2(DAC)
nTotal DC output current on all I / O lines: 130mA
nDC current for 3.3V pin: 800mA
nFlash memory: 512KB all available for the user applications
nSRAM: 96KB (two Power Banks: 64KB and 32KB)
nClock speed: 84MHz
