[[Image:DUE Mini 1.jpg]]

Iduino DUE Pro board derives from Arduino Due. It is completely compatible with Arduino Due. The microcontroller board also is based on

the[http://www.atmel.com/Images/doc11057.pdf  Atmel SAM3X8E ARM Cortex-M3 CPU ] .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.Users could program it with Arduino IDE([http://arduino.cc/en/Main/Software   Arduino v1.5.2 Beta:]).


We made some changes on the original board,because if you got the Arduino DUE board, you will feel on it is: oh, so complicated! While you found you could 

program it through both USB port. We think, why not remove one and leave users more chances to develope on another , it could make the board simple. As 

ATmega16U2 circuit takes very much space on the board, we decide to remove it. And all the pins for external programmer are broken out. 


Of course ,it is more cost-efficient  external programmer uses the [http://www.atmel.com/Images/doc7799.pdf  ATmega16U2 ]as a USB-to-serial chip connected to the first UART of the SAM3X . 

Similar with boards such as Arduino Mini or Arduino Pro, many board could share one external programmer.If you need 10 boards to build your projects,you only need 

one external programmer. That will save you much money.


'''Warning: Unlike other Iduino boards, the Iduino Due Pro board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages, like 5V to an I/O pin could damage the board.
'''

'''Note: DUE Pro USB/Serial Adapter don't plug in the header to Iduino DUE Pro board when power on from the DC power jack .'''


== Differnece from Arduino DUE ==

1.Oscillator for RTC is assembled

2.Removed the ATmega16U2 chip, break out programming pins for external downloader.

3.5V Serial interface is available


== About DUE Pro USB/Serial Adapter ==

[[Image:DUE Mini USB1.jpg|500px]]
[[Image:DUE Mini USB2.jpg|500px]]

The DUE Pro USB/Serial Adapter is designed based on the ATmega16U2 circuit on Arduino DUE. With the bended female header, users could plug in the header to 

Iduino DUE Pro board.

== USE ==

'''1.Programming from USB on the board'''

To use this port, select "Arduino Due (Native USB Port)" as your board in the Arduino IDE. The USB(the one closest to the reset button) port is connected 

directly to the SAM3X.Connect the  USB port  to your computer.

'''2.Programming from DUE Mini USB/Serial Adapter '''


[[Image:DUE Mini 3.jpg]]


To use this port, select "Arduino Due (Programming Port)" as your board in the Arduino IDE. DUE Pro USB/Serial Adapter plug in the header to 

Iduino DUE Pro board,and connect to your computer.
