I use the nucleo-f446re board and this part gets very hot.

When I connect to my computer with a USB connection to upload the code to the nucleo-f446re board, that part of the board gets very hot. I didn't forget to jump to the U5V all the time when I connected to the computer with the USB. Why does this happen? Currently, that part gets very hot and the board is not recognized well by the computer.

Hello @coolingmaster 

Change USB cable and try one for data connection (not a charging cable). 

Check power and ground and circuit around VCAP pins.

I connected it with the data cable that I always used. This doesn't happen when I buy the board for the first time and connect it the same way. But now, when I connect it to my computer using a cable, that part gets very hot within seconds. Where is the VCAP pin? I'm connecting the board to the computer without anything on it right now.

Probably the chip and/or board has been damaged. Is it on a conductive surface? I'm guessing it's on sitting on your keyboard when programming. Can you still connect/program the chip with STM32CubeProgrammer?
