The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU (datasheet). 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 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. specifications: • Microcontroller: AT91SAM3X8E • Operating Voltage: 3.3V • Input Voltage (recommended): 7-12V • Input Voltage (limits): 6-20V • Digital I/O Pins: 54 (of which 12 provide PWM output) • Analog Input Pins: 12 • Analog Outputs Pins: 2 (DAC) • Total DC Output Current on all I/O lines: 130 mA • DC Current for 3.3V Pin: 800 mA • DC Current for 5V Pin: 800 mA • Flash Memory: 512 KB all available for the user applications • SRAM: 96 KB (two banks: 64KB and 32KB) • Clock Speed: 84 MHz Category: ARDUINO BOARDS
