Mavic Mini (A Look Inside)

[Piranha]

Thanks for the pictures and info! Is it FCC model? Would you be so kind to share picture of rf part marked by red arrow?!!!

Your arrow looks to be directly over the amberella image proc SOC, to the right in the RF shielded enclosure the main chip is an Atheros Wifi radio AR1021X-CL3D.

I tough it’s obvious that I was talking about missing part of the image (right side) where RF part of the board located sorry for my English
I’m asking because on the CE board, above atheros is a missing(unsoldered )chip My guess - amplifier! So if on FCC the chip is there-thats the difference

Nothing wrong with your English- there is a lot to the right where the photo doesn't cover.

If you look at the material submitted for FCC approval it seems DJI does not make different versions of the controller or aircraft- the radio performance it set for FCC/CE etc by firmware flashed at factory.

so to be little bit more sure its easy to compare photos of CE and FCC boards but nobody does show fcc picture yet

Parrot anafi motors don't work on mavic mini either... When putting them on and turning mavic mini on you get a power error. Just in case anyone was wondering

Yes you can . I'm working on adding additional batteries now... I've even replaced the 2500mah 18650 cells with 3500mah 18650cells. However no flight time was increased because the batteries I used were only rated for 10amps not 20amps... Looks like the best we can do for 20amps is 3000mah. That will at least put us in the 30+min flight time mark. Then add 2 3000mah 18650s on top, tapped into these solder points and we should be good for 45min +

Hello from Tampa, interested in your experiment! Would be awesome to achieve such a feat.

I'm eager to learn how I could make this happen myself. Please update me on your progress. Cheers!

You would need to connect your auxiliary cells in series and then in parallel with the B+ and ground connections from the OEM battery. Those solder pads are almost certainly for the logic circuits on the ESC board. Wrong voltage and on the wrong side of a voltage regulator to feed motor drive investor mosfets. If your lucky it will be a waste of time I suspect though your will end up killing components.

I will complete it this week. Probably tomorrow actually. At least you're close by, if I succeed and it's worth while I'll ship you a unit.

 

[Piranha]

But maybe you have a photo I asked before? Would help me much ?

Can I use that scheme + and - for fast charge of battery mavic mini with imax6b....

Can I use that scheme + and - for fast charge of battery mavic mini with imax6b....

I wouldn't because that won't Ballance the cells

Can you help me ....suggestions

AR1021X-CL3D is dual-band, does it mean that we’ll be able to unlock the 2.4GHz through software?

We can only go by what DJI has revealed in the FCC certification submissions- the differences aren’t in hardware they are set in factory installed firmware. To the extent that might be able to be altered by the end user is, or at least seems to be at this point, unknown.

Will perform a test flight tomorrow. But everything works perfectly...

Very nice- where did you connect the power?

 

[Justinswidebody]

I soldered onto the 2 pins. Unlike the mavic pro, you can plug the battery in whenever you want. Just can't fly it without a stock battery in. If you try that, you get power error.
