Description of Arduino Due Board: Fast 84 MHz, 54 I/O pins with 2 DACs, large 512 KB flash memory. The Due is the first Arduino board to feature a 32-bit ARM controller. The fast clock speed of 84 MHz, combined with a total of 54 I/O pins, allows you to realize very large projects. At the same time, the simplicity of a typical Arduino system is maintained thanks to the extensive Arduino libraries and compatibility with most Arduino shields. Among the 54 pins, there are 12 PWM outputs and 12 analog inputs, as well as 4 UARTs, 2 TWI (I²C), and a dual digital-to-analog converter, which is particularly suitable for stereo sound outputs. A dedicated USB host provides the board with a wider range of options alongside standards like JTAG, SPI, and Micro-USB. The memory is tailored to the high processor speed with 512 KB flash and 96 KB SRAM. Technical specifications: Model: AT91SAM3X8E, Operating voltage: 3.3 V, Flash memory: 512 kB, Power consumption: 800 mA.
