Note: This is not the same as other UNO boards, the  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.  ARM core strengths  The use of 32 bit ARM core Due compared to the previous use of the other Iduino core 8 AVR more powerful.  The main differences are:  * 32 bits at a clock can process 32 bits of data.  * CPU clock frequency of 84Mhz  * 96 SRAM KBytes  * 512 Flash KBytes  * A DMA controller, can reduce the pressure on the CPU to do a lot of computing  Features:  Microcontroller: AT91SAM3X8E Operating Voltage: 3.3V Input Voltage (recommended): 7-12V Input Voltage (limits): 6-16V Digital I/O Pins: 54 (of which 12 provide PWM output) Analog Input Pins: 12 Analog Outputs Pins: 2 (DAC) Total DC Output Current on all I/O lines: 130 mA DC Current for 3.3V Pin: 800 mA DC Current for 5V Pin: 800 mA Flash Memory: 512 KB all available for the user applications SRAM: 96 KB (two banks: 64KB and 32KB) Clock Speed: 84 MHz Package Includes: •1 x AT91SAM3X8E DUE Board
