Description:1) Since the board operates at 3.3 V, the maximum voltage that can be applied to the I/O pins is 3.3 V. Supplying higher voltages (e.g. 5 V) to the I/O pins may damage the board.2) Advantages of the ARM core: Using a 32-bit ARM core is more powerful than the other Iduino cores previously used with the 8 AVR.The main differences are:- One clock of 32 bits can process 32 bits of data.- CPU clock frequency is 84 MHz- 96 KB SRAM- 512 KB of flash memory- A DMA controller to relieve the CPU of a large number of calculations.Specifications:- Microcontroller: SAM3X8E- Operating voltage: 3.3 V- Input voltage (recommended): 7 - 12 V 7 - 12 V- Input Voltage (Limit): 6 - 16 V 6 - 16 V- 54 digital I/O pins (12 of which provide PWM outputs)- Analogue input pin 12- Analogue output pin 2 (DAC)- Total DC output current for all I/O lines: 130 mA- DC current at 3.3 V pin 800 mA- DC current at 5 V pin 800 mA- Flash memory 512 KB, all for user applications- SRAM: 96 KB (two banks: 64 KB and 32 KB)- Clock speed: 84 MHz
