How can I fix this ESC circuit?
Thats too bad, thankfully the solution is easy(ish)


Read the top of the other chips next to the blown one (I am optimistic that they are all the same)
Google the part number (typically the first/top line), and order a replacement (good sellers are digikey and mouser)
Clip the 2 legs of the blown component
Desolder the legs, be careful not to lift the pad!
Let the board cool for a bit
Desolder the component, again be careful not to lift the pad..
Let the board cool for a bit
Clear off the old solder with some solder wick.
Let the board cool for a bit
Solder the replacement on.


When desoldering, I like to heat up the component and then with my other hand, grab the component with tweezers. Sometimes, it actually helps to add solder to the part, if it is being especially stubborn. Always watch and make sure that you are not about to lift a pad.

In case the worse happens, and you lift a pad, use your eyes, and if needed a multimeter to find out where the trace on the board goes. Solder a wire from where the lifted pad was, to where the trace goes. Just pay attention to how much energy is flowing through the wire, and properly size the wire.
