Is normal than the flight controller this very hot?

in the part of the square big is very hot


(también hablo español)

No, it’s not normal.

You have either a faulty controller or crossed up wiring.

Start by disconnecting all plugs and power by USB.
Does it still get hot?
If yes, faulty controller.

If not, plug one thing back in and check until the last thing plugged in causes the hot CPU.

ohh thanks very much for your help :slight_smile:
