Shout out to Jack one of our skilled techs for putting this together
Hi....would be intersting to see some detailed shot from the wifi module opened up to see the stuff underneath the cover...especially from the ce version. Is that possible that you share some detail shots? Thx in advance 
What do you hope to learn. The software radio is an Atheros AR1021X-CL3D with encoding and data stream prep being performed by the Ambarella H22. We know from statements DJI had made in the various compliance certification application documents there is no hardware differences we should expect. FCC/CE performance differences are determined by factory flashed firmware modules.Hi....would be intersting to see some detailed shot from the wifi module opened up to see the stuff underneath the cover...especially from the ce version.

We want to make sure they 're the same
I can 't find any documentation on Atheros AR1021X-CL3D. Can You give me datasheet for AR1021X-CL3D? Do you think there are no signal amplifiers between this chip and the antenna?
I was truly proud that DroneDJ made note of whom provided the actual images.
I only posted the 4, but have many others.

And yes, it will reveal my true name. However, just remember, I am the TMZ of the drone world! AkA @Drone Master

I had a quick look at the article.It seems to be a lot of conjecture about employment of a H22 or other Ambarella COC in a future Mavic.I was truly proud that DroneDJ made note of whom provided the actual images.

Do you have anything that might help @Hawkins2000 with his question about radio hardware differences (if any) between mavic mini models?
DJI has said the hardware between models is the same- the differences in radio performance are implemented with factory flashed firmware. Why the need to doubt? That would be what we should expect even if only from a manufacturing perspective.We want to make sure they 're the same

Even if its firmware its probably hard firmware that can't easily be gotten to by external means. Many Systems on a Chip (SoC) have a portion of their flash that can be locked, in some cases permanently by a fusable link and in other cases the data is completely wiped if unlocked.

Not so much a specific next project idea as a general suggestion- to include, to the extent your technicians are able to do so, technical information explaining the function and interaction of the specific components and sub-systems. Im sure many would, for example, have an appetite for learning the intricacies of how the transmission system is implemented. It seems in the mini the "enhanced wifi" is nothing more than DJI leveraging the efforts of Ambarella in employing the on board networking architecture of the H22 and a generic wifi radio and linear RF amp. As seems to be the trend DJI has little to say publicly about light bridge, occusync, enhanced wifi etc. The clues tend to be from Ambarella, Analog Devices and the others who provide the enabling tech- I'm sure any further insights would be well received.

Please, show high quality photo of Radio module (where AR1021X + two chips between AR1021X and antenna) and name this chips. P L E A S E ! ! !
If you are so intimate with the internals perhaps you can help out @Blithe74- he is like a dog with a bone trying to learn what the RF amp chips are..... it looks like DJI has either deliberately removed the numbers or were over zealous with the conformal coating.I was truly proud that DroneDJ made note of whom provided the actual images.

I don’t think you will get an answer in a hurry- the IC’s don’t have readable markings. Might get somewhere scratching the coating off them.Thanks for solidarity
