Hey

Somehow fried my OmInibus I am afraid


I use the following clone: https://www.banggood.com/Betaflight-F4-F...03940.html


You can see my wiring in attachement, I used a direct connection from the lipo to get the FC powered (vBat and ground). Checked the setup first with my multimeter for shorts and used a smokestopper to protect FC and other electronics.




I measure 12 v from the 3S lipo going in but then all other connections are dead no way to find any voltage. FC has no LED's that light up. Also when connecting only with USB no LED's.


Any idea's

Welcome to IntoFPV!

I don't know if I'll have enough experience to tell you what's wrong for sure but I know enough to ask some questions that might help some of the more experienced folks help you out.

Based on the photo can you confirm that you're connecting power to the 3rd row from the top or 4th row? The pins are coming out of the 4th row but I can see the
solder in the 3rd row.

The 3rd row is the correct one for power. I power directly from 4s lipo to the VBAT and GRND pins on my bumblebee build (which has the exact same FC) The board has the built in voltage regulator and can manage direct lipo power.

It's a little tough to see the joints for the motor outputs. Is there a reason you didn't solder directly to the pads rather than use the pins? Have you used a multimeter to test for continuity between the motor signal outputs just in case it has something to do with the joints on the pins?

Also it looks like your RX isn't hooked up. Was it not hooked up when the problem happened?

Hallo

Thanks for the reply, and yes you are spot on I miscounted in the pin's, powered from the 4 th row meaning pin's GND & CRNT.

I resoldered the pin to the 3th row and powered up. Still no LED's on the FC, I do measure 5V however between GND and 5V pin's. So I did not fry that part.


NO way to connect it to betaflight.


I orederd a new one on bangood should I take the same or the pro version?

Being able to use a microSD card for blackbox is nice but it's up to you as to if that's important enough. If you've already ordered then I'd say to go with whatever you've ordered and not worry about changing it.

Hey

A little sequal, so last time I fried my FC by connecting to the wrong pins. Ordered new one and started setting it up.

All was fine, motors spinning setting up my flysky receiver, etc. Used the tutorial of propwashed. Had a little issue with config, because i placed my flight controller in the wrong orientation. Fixed that also by adding the angle at wich i turned it

Now it comes seemed to have lost the connection to the receiver, checked all the pins but nothing, i used PPM it worked perfect 5 min before.

And then I did a daft thing, tried to set up an IBUS. Connection. Used the other connection on the receiver. Modified the receiver connection setup in betaflight.

While setting up I lose connection to the FC via betaflight, restarted PC reinstalled the required USB ports but nothing ...

Leds still blinking but no way to make a connection, did i waste another FC ???

Are these so sensitive what did I do wrong ???

SOLVED

I solved it !!!!


 The FC was not fried. But I did need to Flash is after resetting it with the boot buttom. It was an strange combination of losing the USB connection (related to Norton I believe) and the FC losing the connection of the RX at the same time.

from one magic blue smoke maker to another,....
i hate to loose communication with a flight controller
many of the newer boards now have voltage/short protection
did you try to boot/flash your old board? it may take a try or two.
