Original Arduino DUE Arduino Due is a microcontroller 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 features 54 digital input/output pins (12 of which can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), an 84 MHz clock, a USB OTG capable connection, 2 DACs (digital to analog), 2 TWIs, a power input, an SPI header, a JTAG header, a reset button, and an erase button.
Important: Unlike most Arduino boards, the Arduino Due operates at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying a voltage higher than 3.3V to any I/O pin m Show More
