32-bit Arduino

At last the Arduino team have announced an official 32-bit ARM board.

The specs look pretty standard for a ARM Cortex-M3 but they’re nice specs none the less.

The uC is a SAM3U processor from Atmel with the following specs:

  • Speed: 96MHz
  • Program Memory: 256Kb Flash
  • Data Memory: 52Kb SRAM
  • Digital I/O: 5 SPI buses, 2 I2C interfaces, 5 UARTS
  • Analog I/O: 16ch 12-bit Analog Inputs.

Not sure of the PCB package size but it looks like a 100 or 144 pin TQFP.

I’m not sure if the SAM3U uC is 5V tolerant, which could be a problem for some 5V only shields.

On the whole the 32-bit Arduino looks like a winner, now lets hope the 32-bit Arduino software is as good as the hardware.

    Hi Tony,

    this together with your XArduino shield looks like a hell of a beast. Do you have any updates to share about it (and your x-one)? I can’t find any news on them… how far did you get / what’s missing? Do you plan to share your work?

    Thank you!
    Stephen
