Iduino DUE Mini
Overview
Iduino DUE Mini board derives from Arduino Due. It is completely compatible with Arduino Due. The microcontroller board also is based on
theAtmel 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(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 we found we 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 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 Arduino boards, the Arduino Due 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.

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 port is connected directly to the SAM3X.
Connect the USB port (the one closest to the reset button) to your computer.
2.Programming from DUE Mini USB/Serial Adapter
To use this port, select "Arduino Due (Programming Port)" as your board in the Arduino IDE. DUE Mini USB/Serial Adapter plug in the header to
Iduino DUE Mini board,and connect to your computer.
