Custom PCB unused interfaces.


I am designing a custom PCB that will be as barebones as possible, which I am basing upon the awesome opensource Antmicro Jetson Nano Baseboard.

I don’t need the displayport/ethernet/Camera, so can I just delete these from the schematic essentially leaving the pins from the SOM floating?

For example:

I only require HDMI, can I just delete all of the display port circuitry that I have highlighted?

Hi, you’d better to check with vendor first. For Jetson nano, it is OK to remove other IOs and only leave HMDI. You can check the OEM DG, there is guide in it that tells how to handle the unused pins (most can be leave floating).
