Hey Guys,

This is my tutorial on the Diatone Mamba F722 mini FC that I recently installed on my Gecko frame.  Actually I swapped out and existing Diatone mamba F405 because I broke the USB port.  I decided to put the F7 because of the extra Uarts and plus this had a barometer.  There will be a part 2.  Let me known what you think.

Wow is a tight fit on the Gecko frame.

Hi cisco,

That is a really NICE Tutorial video 

Nice video man! Very good production value. I actually found this helpful as I just ordered the DJI version of this board. Thanks for sharing.

Nice video!
Yeah the MK2 F405 USB sucks big time.. My 3 one broke.. oh well u get what you pay for.

I have started applying additional "security" to the USB connector on ALL of my FCs regardless of brand or type. At this point, I am using Bondic which is a UV curable liquid plastic. It seems to work well...so far, the FCs where I have secured the USB in this manner have remained intact and have not come off.

Yeah let me order one from Amz.. thanks.

Another way to mitigate the broken off USB socket issue is to keep a special USB cable that isn't a tight fit in the socket. A lot of the problems stem from the constant plugging in and unplugging of a USB cable, and if it's a tight fit then each time you do that you are putting unnecessary force on the socket which is only held in place with solder. I have one specific USB cable that is dedicated for use with my quads only and it slides in and out of the socket with no force needed at all. I have never broken off any USB sockets using that cable, and my very first quad which I still fly has had literally hundreds (maybe even over a thousand) connections and disconnections using that USB cable with no sign whatsoever of the socket having been damaged or weakened.

Hi Snow,

Sounds like a good idea. Thing is, I am not sure how to make a cable fit "loose". Also, I only have 1 (or maybe two) cables that will actually work due to the large plastic housing on the USB cable. In fact, the one that I use, I had to "whittle" down with a knife to be able to use it. Anyway, good idea.

How my USB connector broke was handling the craft after plugging the cable in.

Thank you.  I believe the DJI is more Air Unit friendly since it has the voltage regulator.  That's good to hear.

Thank you!  That happened to mine too.  I'm not sure if I mentioned it on my video.  I actually soldered back on but didn't work as well.

I installed a right angle USB cable on my franken bugs3 FC  because of that, i cut the 1 foot cable (usb ) to about 6 inches, and leaved the USB A pigtail wire tied to a leg of the quad
that way the stress is on the pigtail and no on the FC USB port
