  • Contains everything needed to support the microcontroller
  • Power it with a AC-to-DC adapter or battery to get started
  • Compatible with all Arduino shields that work at 3.3V
  • Arduino board based on a 32-bit ARM core microcontroller

The Arduino Due 32bit ARM Microcontroller 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 analog inputs, 4 UARTs (hardware serial ports), a 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.

The Arduino Due can be powered via the USB connector or with an external power supply. The power source is selected automatically.
External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector.
The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.
The power pins are as follows:
  • Vin. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or if supplying voltage via the power jack, access it through this pin.
  • 5V.This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it.
  • 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 800 mA. This regulator also provides the power supply to the SAM3X microcontroller.
  • GND. Ground pins.
  • IOREF. This pin on the Arduino board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.

genuine device plus extra

More $$ for this board than from Shenzhen but you avoid the Rev3 10k resistor failure documented here That is, these boards include this DUE correction. Yessir. There is also a custom fabricated header (despite that beige? is a dreary colour choice for this item) with pin labels — this is much welcomed when routing to the +100 pins. Aaaand, it's got a comfy transparent base that will allow your lab partners to take your powered DUEs and set them on a pile of metal bits — and voila, nothing shorts out.

Powerful processor

This board has more CPU power than other non-OS-based boards from Arduino. For real-time closed-loop applications where a non-realtime OS would introduce jitter, this board is a great option. Occasionally we had an issue in the past where the board would squeal audibly when an external circuit was powered from the Due's 5V pin, but this seems to be resolved in the latest batches of boards. I'm very happy with Arduino's high end processors, and I hope an M4 board (i.e. Star Otto or equivalent) becomes available soon.

Fast Shipping, Original Products

Thank you for ship my order very fast, but next time I hope you place better protection on your package, you can separate different product with bubble wrap, so package for every product still good Robotshop always ship original and high quality products :)

For further.

Impressive map that takes you to another level. It takes time to learn it. It has its own Real-time Clock (RTC)

Jean Pierre
It is a beast comme on dit

It has its own Real-time Clock (RTC), power (800mA) which can save you from having to use additional transistors on occasion. It is at a higher level but for passionate beginners why not give it a try right away?
