Arduino Due Development Board A000062

Description

The Arduino Due stands as the inaugural Arduino board to feature a powerful 32-bit ARM core microcontroller, specifically the AT91SAM3X8E. This board offers an extensive array of connectivity and processing capabilities, including 54 digital I/O pins (12 of which support PWM), 12 analog inputs, 4 hardware UARTs, and an 84 MHz clock speed. Further expanding its utility, it integrates USB OTG, dual Digital-to-Analog Converters (DAC), two Two-Wire Interfaces (TWI), an SPI header, and a JTAG header for advanced debugging and programming.

It is crucial to note that, unlike traditional 5V Arduino boards, the Arduino Due operates natively at 3.3V. All I/O pins are strictly 3.3V tolerant; applying higher voltages can result in irreversible damage to the board. Designed for ease of use, the Due can be powered via a micro-USB cable, AC-to-DC adapter, or battery. It maintains compatibility with a broad range of 3.3V Arduino shields that adhere to the 1.0 Arduino pinout standard.

The board’s 1.0 pinout enhances shield compatibility, featuring dedicated TWI SDA and SCL pins near the AREF for streamlined I2C communication. The innovative IOREF pin allows properly configured shields to adapt to the board’s operating voltage, facilitating seamless integration with both 3.3V Due and 5V AVR-based platforms. An additional unconnected pin is reserved for future expansions and functionalities.
