Thread: Shiny new toy: ODROID-U2

  1. Shiny new toy: ODROID-U2




    It just arrived today
    The ODROID-U2, with an ARM Cortex A9 quad-core at 1.7Ghz and 2Gb RAM is what I hope will be the visual cortex of my next beast, that is currently intended to be a fun little MechWarfare quad (more on that in an undisclosed period of time). There might be a BeagleBone Black (that I will receive tomorrow ^^) in the same bot too, one can never have too many power hungry brains in a bot


    Unfortunately I kind of forgot to put the power plug in the basket before checking out, and the power plug is smaller than anything I have around (inner(positive) diameter 0.8mm and outer(negative) diameter 2.5mm) so I haven't powered it yet. I'll put one in my next element14 order.

    I chose the eMMC (16Gb) option for the "hard drive" since it seems to be a good way to get rid of the sluggishness of uSD cards (especially for small files). The eMMC module is, as the rest, extremely tiny

    After removing the case / heat sink, I've been a little disappointed to see that the thermal pad did not have more than 60% of its surface in contact with the processor :/
    The threaded metal insert soldered on the PCB are a nice touch, too bad one is not perfectly aligned (I suspect that's the reason why the pad did not make better contact, I'll correct that).
    My feeling is that the gigantic heat sink is not really necessary, (the Galaxy Note doesn't have 200g of aluminum in it after all), I'll remove it and use the robot's chassis to dissipate the excess heat instead.

    The eMMC has a little bit of foam double sided tape that you can use to secure it more firmly, nice attention to details. I'll keep the protective layer on until I'm sure I'm satisfied with the OS configuration.

    And here is a little size comparison with some common other boards: Arduino UNO (top right), Pandaboard (bottom right), Raspberry Pi (bottom left).



    I have no idea when I will have time to play with it, so many toys... but at least I have a specific idea about what I want this one to do, so do not fear, I will get to it

    That is nice! BTW, how is USB2AX sales going? I getting ready to buy a couple more.

  3. Re: Shiny new toy: ODROID-U2

    USB2AX are moving slowly... there is much to be said about making your own product, it's for sure an interesting experiment: lots of things do not work the way I expected it ^^ The price when you make something like that is simply not competitive, on such a product nobody can make any money, so it's not really interesting for distributors other than as a gateway to selling more stuff. A few have been sold on Seeedstudio, some have been sold to distributors who haven't put it in their catalog,... Not really what I expected!
    You can always get some at the current distributors listed at http://xevelabs.com/

    I've used them on a few projects now. They are great. I'm half tempted to buy a few just so I have spares. (Not that I have had any fail.)

    I'm definitely looking towards getting one for future use. The USB2AX that is, but possibly an ODROID as well

    With only 2 USB ports, how will you integrate WiFi, Webcam, and servo control? Using some other header for pushing a servo control signal out?

    It is not obvious at all since the last picture is taken with a (large!) Wifi dongle, but I might connect the ODROID-U2 with the rest of the robot... by ethernet (with an on-board wifi router, these things can be so small these days...). I don't have a definitive plan about that right now, too many unknown. If I finally decide that USB is the way to go, then I'll just add a hub like I have on Xachikoma, but I hope I can do without

    In fact, I have some crazy plans for the hardware of the robot, I don't even rule out the possibility to modify the board(s) to fit better my needs(removing unused parts). Oh, and it is even possible that servos will have a little twist too... I can't say more now since it's very very much just an idea right now (i haven't even) started the CAD).

    Looks like a lot of nice toys to play with. I am tempted to order one as well, but so far I have resisted.

    I broked down and ordered ops: along with 16gb emmc, plus Wifi, Plus power, plus debug cable... Not sure yet what I will do with it, but could not resist.

  10. Re: Shiny new toy: ODROID-U2

    Mouhahaha, another one has been contaminated ^^

    BTW, I received my BBBk today, it's big next to the ODROID-U2... but it's also so flat next to it!
    Damn giant USB+ethernet connector, I think I'll just remove it before putting the board in the robot, and either move the connectors at the end of a cable or just solder the peripheral on it, depending on how much available room I will have. It won't be fun though, there are numerous very small SMD chips (0603 to 0201) all around the connector's solder joints...
