Presentation

The Arduino Due card is based on the Atmel AM3X8E ARM Cortex-M3 Microcontroller.

It's the first Arduino board which has a 32-bit microcontroller 

She has:

• 54 entries/digital kinds (of which 12 can be used as PWM outputs)
• 12 analog inputs
• 4 UART (serial port hardware)
• 2 DAC (digital-to-analog conversion)
• 2 TWI
• 1 SPI
•  JTAG connection
• a 84 MHz quartz oscillator 
• a USB OTG connection
• a USB programming and debug
• a power outlet
• a reset button.

It contains everything needed to fly the microcontroller, simply connect it to a computer with a USB cable to use it simply.

Map Arduino DUE respects the standard arduino 1.0 pinout.

Attention: The Arduino DUE card works in 3, 3V. All pins are therefore accepts a maximum of 3, 3V, if inject you a higher voltage as the 5V, it can be destructive for the card.

Package

The Arduino Uno is available in two version, DIP and SMD.

The functionalities are identical is only the package of the micro-controller ATmega328 changing (see photos)
