In this video, I am repairing a Diatone Mamba F405 Mini FC. The MCU was killed so the solution is to transplant a good MCU from a killed PCB. The repair was a success!
Hope these videos are welcomed, they take a lot of my time to create and I pretty much would like to know it helps out people that want to repair their gear.
Thanks!

Livyu videos are the #1 repairing videos SO FAR!!!!

@fernandobaroni1497 2 года назад

Fantastic tips!!

Another great video. Can't wait to get my new digital microscope Monday so I can start rebuilding a 20 by 20 Stack with new components and some strong solder joints 😁

@planetpower6686 3 года назад

Thank you for the in depth repair videos you create. Actually these are the type of content I enjoy the most. Learning how each component works and having the know how on how to do my own repairs is extremely helpful in this hobby for the long term. Thanks again and I look forward to more content from you.

@WildpixFPV 3 года назад

Thank you again for this. Being able to watch you work so closely, even if I don't repair stuff like this (yet?) helps me understand how to be better with the solder wig, flux and all of this. Quarantine is perfect for learning from you! xD

I literally just did the same thing to the exact same board.

@CarbonGlassMan 3 года назад

I'm curious. Would it help the MCU solder melt easier if you add leaded solder to the legs before you try to remove it with the heat gun? I have this same board that has a bad MCU and am planning on repairing it once I order a hot air gun.

@LivyuFPV 3 года назад

if you don't have a hot air gun, and order a fresh MCU, cutting the legs one by one with a fine tip cutter would work also. After that just desolder the legs and solder new MCU leg by leg or by solder drag technique.

@CarbonGlassMan 3 года назад

@@LivyuFPV I did that to replace a 3.3v regulator. A hot air gun is my next purchase. I just wondered if adding leaded solder to the lead free solder holding the MCU down would lower the melting temp of the lead free solder that's holding the MCU down. These repair videos you do are great. I never would have thought this kind of repair could be done until I seen you showing how to do them. I've ordered 3.3v regulators and a couple F405 MCUs so I can attempt this kind of repair. Unless a guy is rich, China's quality control makes this repair skill a necessity. I have at least $200 worth of boards that are junk unless I can repair them and I've only been in this hobby since May.

@LivyuFPV 3 года назад

@@CarbonGlassMan Yes, it will lower the melting temperature.

@xiaoandyh.9282 3 года назад

I just thought could you make a video on how to check for errors on a Bord like this. I Guess not always you see burn marks that determines it’s dead. For example I have a spendix where the cpu gets hot but so I guess it’s that but not sure. Any procedure you recommend. Like check certain power rails or something like that. Like your videos and looks so easy:)

@LivyuFPV 3 года назад

3.3v power rail. If MCU gets very hot then it is probably that one.

@fishballfpv9063 3 года назад

Dang!do you have any recommendation for someone who is jumping in to the world of electronics? because of FPV and a lot of broken electronics i decided to learn about electronics but no idea where to start...

@marcfauve6971 3 года назад

Same here ;)

@christopherj3367 3 года назад

I have a Matek F405-STD Flight Controller same chip, but trying to find the problem has become a pain, I've removed the MCU STM32F405 plus 2 diodes and 2 3.3v regulators BUT I still have a short on the ground to 3.3, I assume its a capacitor that's shorted?

@flat-earther 8 месяцев назад

did you figure it out?

@dukevah 3 года назад

Great video, thanks. I have the same fc. When I connect it to usb, mcu becomes so hot sich that it can burn my fingers. If I am qucik enough, I can connect it to bf so it seems mcu is fine. I checked shorts in pins and there is nothing. I wonder what can be the reason?

@LivyuFPV 3 года назад

they can go bad half way. I would change it for sure !

@dukevah 3 года назад

@@LivyuFPV thanks. I didn't know that it can go bad half way

@habag1112 3 года назад

I have a 30x30 mamba with the same issue, from what I understand it can be 2 things: broken mcu or broken voltage regulator (either 5v or 3.3v, check if the outputs of these regulators are shorted to ground and if they aren't check if they output the correct voltage)

@flyingdream777 3 года назад

Hi , any chance you can do a DJI FPV teardown so we can understand system and internal protocols - I would love to install HDMI Out and possibly AV out, HDMI In could also be use-full in future. thanks for your awesome content always so interesting

@LivyuFPV 3 года назад

Hi, I am waiting for a DJI air unit to try and repair it. But for the Video stream out on the USB-C from the goggles... a really good software guy could hack it and make the video out possible. Hope someone will have the time and willingness to do it.

@changeagent228 3 года назад

HDMI video out has been done. Use SBC and Altera linux. m.facebook.com/gregorioperezperez/videos/10159049166057745/ I want to know of we can locate and upgrade the microphone. Also I hear the radio can go much higher output power. It would be good to inspect the IC's to confirm that.

@flyingdream777 3 года назад

Thanks guys will check it out immediately.
