Arduino Due Development Board
Arduino Due Development Board overview
The Arduino Due is an MCU board based on the Atmel SAM3X8E ARM Cortex‐M3 CPU. It is the first Arduino 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 analogue inputs, 4 UARTs (hardware serial ports), an 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analogue), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button.
The Arduino Due module supports connection and interaction with other USB devices capable of working with the OTG function (On-The-Go - simple and easy connection of devices to each other directly, without using an additional link computer). The board also comes with a wide variety of protection features such as ESD protection and overvoltage protection.
