What is an “X” sign? (In this context).

I want to place the highlighted sign in picture, and probably it is used when a pin is not used(my understanding, I never read that any where).

PS: This picture belong to CM4 official I/O board schematic.

Thanks

It’s on the toolbar on the right side of the screen:

Or: Eeschema / Place / No Connect Flag [Shift + Q]

And these are indeed to indicate to KiCad that you really meant to leave this pin open so ERC won’t generate an error for it.

Thanks for your response, it helps.

“No connect” is a feature of the schematic not the symbol. You can add a no connect symbol from the right hand menu bar or by using the Q key.

You really shouldn’t just copy a schematic you don’t understand.
