ARM Core benefits

The Due has a 32-bit ARM core that can outperform typical 8-bit microcontroller boards. The most significant differences are:

  • A 32-bit core, that allows operations on 4 bytes wide data within a single CPU clock. (for more information look int type page).
  • CPU Clock at 84Mhz.
  • 96 KBytes of SRAM.
  • 512 KBytes of Flash memory for code.
  • a DMA controller, that can relieve the CPU from doing memory intensive tasks.

    Very powerful in comparison with MEGA and the interfacing with 3.3v devices are easy. Good support available on internet.

    I ordered 3 of these. One was not working, and was changed by Electrodragon, but I have still problems with SPI on the three boards. In comparison, I have two genuine ones that work perfectly. So As it is,I do not recommend this product. It may work on some applications and fail on others.

    There is a bug with the way resets are handled with this board but if you fix it it works perfectly. Highly recommended.
