Product Description


Features:
The Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU (datasheet).
It is the first board based on a 32-bit ARM core microcontroller.
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.
Note: Unlike other for Arduino boards, 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.
