So I recently crash my holybros cinewhoop and messed up the esc board...got a new one the excite same one...wired it correctly doubled checked the wiring...I plug in a battery and get smoke...I unplug go into betaflight get my drone to actually flying off the ground and when I try to connect the vista to my goggles I get a solid red light on the vista if I wait a few moments the vista will turn green and then the drone begins to smoke but the vista will work I can see in the goggles...what could be causing it to smoke and how do I stop it please any could help would be great!

You must have a short somewhere if you are getting smoke.

It's not easy to see much from the small photos attached, but do the following:-

1. Make sure the stripped end of any wires are as short as possible because I can see some excess exposed length on some of your wires which can be in danger of touching and shorting to other wires or components.
   
2. Make sure all your solder joints are good and that the solder isn't spilling over to or touching another pad.
   
3. Use a magnifying glass to check the boards for any stray solder splatters, tiny solder balls, or whiskers of wire that might be shorting something out on the board.
   
4. Use a multimeter to check for any shorts between each of the power rails and ground.
   
5. Check that you don't have anything shorting to the carbon fibre of the frame.

Try using the Imgur pic tool as per this post https://intofpv.com/t-how-to-upload-pictures

 I believe this is what most of us use.

Alternatively upload to something like google drive and share a link to the folder.

I think you should get a smoke stopper for troubleshooting this: https://oscarliang.com/vifly-short-saver-2/
It will be really useful for all of your future builds too.

If you can't spot anything wrong, try taking all the components off the frame, connect them one by one and test with the smoke stopper. This will help you pinpoint which component is causing the issue.
