    Seem like someone already crack open the shell. Likely to be pre-production model, should be interesting to see the different between this and the production model.

    Wow, look at all those chips with thermal paste. Must be processors. Not 24, but the larger ones at least!

    It was 24 Cores, not 24 Processors.

    Quad core on the 4 larger ones and duo-core on the other 4 makes 24 cores, wow! that would be some processing power.

    Thanks for the pics! TU

    Those antenna wires are buried in that thing! :eek:

    Considering what this thing will do, it will need all that processing power.

    Nice find..

    I still don't understand why the board where the IMU is located, is suspended by solder. Is it designed to break on a heavy impact??
    The Phantom 3's are designed this way also.

    The gimbal looks easy to change.

    Hard to tell from this picture, but it look like they may be castellated pads. This is a common technique for mounding boards to each other.

    The hand solder joints on that look a little subpar to me, but it may just be the lighting in the photo.

    Amazing - I hope DJI did enough thermal testing :p

    IMHO, as someone who does a lot of soldering, it looks quite acceptable, esp. for a pre-production unit. I also like how they have adhered the motor wire leads to the main board, used multiple attachment points, and large pads for the solder joints. Well thought out.

    We landed on the Moon with less than 1/1,000 the processing power of the Mavic Pro. In fact, it's probably closer to 1/1,000,000.

    They kinda do, you'd think that stuff would be connectorized. Maybe the production units will be different?

    Those solder joints are perfect from a visual standpoint. No cloudiness or opaqueness of the solder joints that would indicate a cold solder joint. If you are concerned about the slight imperfections in the orbs then that is a by product of hand soldering connection points.

    The majority of the connections on the board are wave soldered which will typically look impeccable.

    The board that has the IMU on it will not "break loose" per se. Actually I could give you a small flat head screwdriver and have you attempt to pry it off the mainboard. The mainboard would suffer lots of damage from the prying motion and the daughterboard would not budge. Poor solder joints on one or multiple pads is much more likely.

    That style daughterboard is attached so that all the pads can be heated using a special air iron that allows all the solder joints to liquefy at once and then one can remove the daughterboard.

    Now if I saw that daughterboard as "socketed" then I would be quite concerned with pins lifting out of the socket. If there are issues with the Mavic Pro I could see the "techs" touching up the solder on those pads that attach the daughterboard as part of a rework process.

    Totally off topic, but the Apollo computing story is fascinating. Here is one of my favorite stories on how the Apollo software was "woven" (literally):

    Look closely at the underside fins and heat sinks as well as the heat sinks behind the camera obviosely thermal management was a major part of the engineering.

    Yes, and a chunk of finned aluminum is also good for stiffening the chassis. It does look, however, that that element is for cooling and it's in the perfect location for it -- out of the Sun and in the air-stream.

    Not wanting to sound like a DJI fan boy, but you have to admire these guys. I mean, it´s not like their drones are so ahead of competition in most regards - features, stability, performance, etc. - but when I think about it I remember that no one has even come close to Lightbridge 2 yet... And they already come up with Occusync and all these features in a $1K drone that small... I find it pretty amazing, no small feat these days!

    I know that many are waiting for their Mavic and I am blessed to have one and have been flying one for several weeks. We are already on our second firmware upgrade and all is well. I really enjoy flying in Sport mode. The craft is super fast and responsive. You can overload the gimbal if you fly like I do. Not an issue for the most part. When you get yours please upgrade, calibrate the IMU and compass. I also did a gimbal calibration. It does not take long and you will be pleased with the results.
