Awsome product at reasonable price
Purchased this as I wanted a 32 bit processsor, too many pins for my requirement and started to use far
The Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. The Due Arduino AT91SAM3X8E ARM Cortex-M3 Board 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 analog inputs, 4 UARTs (hardware serial ports), an 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 Arduino 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 Cortex M3 processor is very well suited for highly deterministic real-time applications Microcontroller Programming in Embedded and low-cost platforms such as industrial control systems, automotive body systems, wireless networking and sensors, and so on.
The Cortex-M3 processor is a 32-bit processor, with a 32-bit wide data path, register bank, and memory interface. A total of 13 general-purpose registers, two stack pointers, a link register, a program counter, and a number of special registers, including a program status register, are available.
The Arm Cortex-M3 is a microcontroller. The 32-bit Arm Cortex-M3 core microcontroller is designed for high-performance, real-time processing in cost-constrained applications and can handle complex tasks. Any Arm Cortex-M3 microcontroller offers high scalability combined with an optimal trade-off between performance and cost.
The Due can be powered either by USB or by an external power supply. The power source is automatically selected. An AC-to-DC adapter (wall-wart) or a battery can provide external (non-USB) power. A 2.1mm center-positive plug can be plugged into the board's power jack to connect the adapter.
The speed of the processor for the due board is much faster compared to the mega board. The processor used in the due board is considered the fastest processor compared to other boards. The other difference between the due board and the mega board is the size of the memory.
