The Arduino Due is the first Arduino board based on a 32-bit ARM Cortex-M3 microcontroller, offering enhanced performance for complex applications. It features 54 digital input/output pins, of which 12 can be used as PWM outputs, making it ideal for robotics, automation, and IoT projects.
With a high clock speed of 84 MHz, the Due is significantly faster than traditional Arduino boards. It includes 96KB SRAM and 512KB of flash memory, allowing it to handle large programs and real-time data processing efficiently.
The board supports multiple communication interfaces, including four hardware serial ports (UARTs), USB OTG capability, SPI, TWI, and JTAG. It also follows the 1.0 Arduino pinout for compatibility with 3.3V shields. The IOREF pin ensures that attached shields can automatically adapt to the board’s voltage.
Simply connect the Arduino Due to a computer via a micro-USB cable or power it with an AC-to-DC adapter or battery to get started. It is an excellent choice for high-speed, resource-intensive projects that require precision and performance.
