The FC is broken. When I plug in a lipo it doesn't do anything anymore If I connect it to my PC on USB it works fine. I can also see it in betaflight
I have a picture to show what is wrong. Who knows what component it is I thought is an inductor. photo is what I see now. Who can help me.

Ps: how can i add photos.

The component that your arrow is pointing to is an inductor as you stated. Those still work perfectly fine even when the ceramic casing is chipped like on yours which is quite common, so that inductor isn't the cause of your problem.

An FC booting up from a USB cable but not from a LiPo means that the 5V regulator on the FC is fried. When plugging in via a LiPo the LiPo voltage is then regulated up or down to 5V via an onboard 5V regulator, but when you plug a USB cable in the 5V regulator is bypassed because the USB provides 5V to the FC instead.

You have one of the following 3 options:
  1. Locate and replace the 5V regulator on the FC circuit board.
  2. Power the FC by injecting 5V into one of the 5V pads using an external 5V BEC.
  3. Replace the FC with a new one.
