Some questions

  1. Did it work before?
  2. Is it recognised if you disconnect evevrything except the USB?
  3. Which operating system?
  4. What does your operating system think about your board (e.g. windows device manager, linux lsusb and dmesg, no idea about a Mac)?
  5. Which version of the IDE?
  6. Do you have a link to the exact Uno that you bought?

1.yes
2.no
3. windows 10
4.windows device manager
5.my ide version 1.8.19

So what does Windows device manager think of your board?
And you did not answer (6). We would like / need to know of you have an original / clone with 16U2 or a clone with another TTL-to-USB converter.

Additional questions that I forgot.

  1. What was all connected to the board when it started failing? Drawing will help.
  2. How was it powered? USB only? External and USB? Drawing will help.

OK, I would like to know the model of the chip closest to the USB port.

Is it square like shown or rectangular with pins only on two sides. To read the type, you will have to angle it in good light and possibly take a macro photo (if your phone / camera has that functionality) to be able to read. The square one is possibly Atmel 16U2, a rectangular one probably a CH340.

If your board is not detected, that chip has probably died. The 16U2 seems to be very prone to power issues (not saying that you can't kill a CH340).

A fuse in the 12V line will protect the power supply, not your board. Was nothing else connected like motors, solenoids, relays etc.

My chip rectangular and removal one is atmel atmega328p pu
