Thread: The Robotis TurtleBot3

    Re: The Robotis TurtleBot3

    What's your experience with the Nano? Have you compared it to other boards?
    I kind of don't see what Nvidia wants with the Jetson Nano. It's the quad core ARM from the Jetson TX1 with half of the GPU of the TX1. It's an old GPU architecture (Maxwell) and as such not particularly energy efficient for what it does.
    It's three times the price of the Raspberry Pi 3, so it has no way to compete for "cheap linux." It's a quarter or less of the throughput of the TX2, although it does have a smaller form factor.
    Is it actually "the sweet spot"?

    The fan was overkill as I have never been able to get it hot enough to turn on
    Once booted onto the USB this is a full on speed demon with V2 camera and as far as I can tell a raspberry PI GPIO or
    something unbelievably close to it. Still playing but I have the full melodic desktop working and am pretty happy so far.
    Check out jetsonhacks he is working hard on the board as well.
    "The Nano is roughly twice the cost (you don't need a case to keep it from throttling), roughly twice the performance,
    4x the RAM, and uses the same power as a Pi 3B+. That's a win, in my book!"

    And a built-in real-time clock chip, so you don't get the wrong time on boot like with the Pi ...
    Worth the price just for that :-)

    LOL and unfortunately there is no RTC (Real Time Clock) on this model.

    Because saving 25 cents was totally worth the hassle of invalid file system timestamps ...

    Every hat/attachment to any Pi connector should contain an RTC ...
