  I am engorged.

  Seems like a cool project, but with such weak specs what can one actually do with this?

    The specs are literally the reason why people would buy this. It’s basically the best possible device for devices handling secure computation. Think of a FIDO2 key, or a gpg smartcard, all verifiable`

      Ehhhh… I’d recommend a Teensy instead, or a variety of other microprocessors. At $72, this is awful value. And there seems to be no specifications with regards to power-consumption.

      Teensy gives you 100 MBit Ethernet, USB, 600MHz, 1024kB of SRAM for like $35 and within ~100mA of current usage at this 600MHz speed, meaning it easily runs off of AA Batteries for over a day with just a bit of idle/sleep cycles.

    This thing is like 5x more MHz with 8x more RAM than an Arduino. 18MHz and 128kB is plenty.

    Remember: the Apollo flight computer (Moon landing) was accomplished with 2MHz and 4096 bytes of RAM. Even the Arduino is more computationally powerful than the Moon Lander.

      So, what? I’m gonna go to Mars with my USB stick RISC-V?

      arduinos run at 16 MHz
