Cheap "high voltage" esc Quest

Here's a picture.

Looks like inductors, do you see any coils inside?

All the rest is clear Fet's drivers with bootstrap caps and diodes.

Also looks like you lost couple via's in process of taking it apart, not good, but can be fixed.

I can try to fix it for you, but later in April :(

I noticed the coupler. I can fix that.

What I'm really wondering is:

Can I remove the regulator altogether and power the brain board with an external regulator that feeds 5 volts IN through the red wire?

I don't see any reasons why not, but looks like you have two DC-DC convertors, so you need to remove diode/inductor/resistors from first one and than check if second one is still working (from smoked inductor I think it is dead too).

So to make it happy again you need to restore 5V and 12V for MCU. How you are going to do that it is up to you. I would rather check datasheet on both DC-DC convertors and fix them properly.

Are you sure MCU is not dead?
