Description
Cortex-m3 CPU
32-bit Atmel SAM3X8E ARM
The Arduino Due is a microcontroller board based on the 32-bit Atmel SAM3X8E ARM Cortex-M3 CPU. It offers 54 digital input/output pins, 12 analog inputs, 4 UARTs, 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.
This is a great board, fast CPU, plenty of memory, a lot of pins. Great when you need to attach a keypad, screen and some extra sensors and actuators. USB HID is a cherry on the top.
Beware - this is a strictly 3.3V device. If something puts 5V on , the pins (in better case) or the whole cpu will stop working. Learning thechard way, I will have to buy this one again (I really liked it) even it cost something
