Arduino Due Without Headers
The Arduino Due without headers 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. 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, 2 DAC (digital to analogue), 2 TWI, power jack, an SPI header, JTAG header, reset button and an erase button. This board contains everything needed to support the microcontroller. You can simply connect it to a computer with a micro-USB cable or power it with an 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.
How to get started:
The Arduino Due already has everything on-board to support the MCU. Simply connect it to a PC via microUSB cable or power it via an AC-to-DC adapter or battery. (Please note these are not included)

Does it work with the Arduino Shields?
Yes, the Due board works with all available Arduino Shields that running at 3.3V and are compliant with the 1.0 Arduino pinout:
- TWI: SDA and SCL pins that are near to the AREF pin.- IOREF: allows an attached shield with the proper configuration to adapt to the voltage provided by the board. This enables shield compatibility with a 3.3V board like the Due and AVR-based boards which operate at 5V.- An unconnected pin, reserved for future use. Arduino ARM Development Boards
Warning
the Arduino Due board runs at 3.3V (which is different to most other Arduino boards). Applying voltages higher than 3.3V to any I/O pin may cause damage.
