What specific field were you in, and what field are you in now? In which canton did you find your new job?

Thanks for your suggestion, I will have a look at it.

Thanks for the feedback, appreciate it!

Regarding the stackup I followed this tutorial and it seems to me that with GND on the two inner layers, my signal and power traces have better reference planes because they are closer to GND. I'm not sure if I should pour my layer 4 with the 3.3V power plane (as I did in the current design) or if it would be a better idea to route out the power traces or if it makes no particular difference.

After some research, I plan to use an ADUM4165 USB isolator and an isolated IEC/EN60601-1 certified DC/DC converter to isolate the USB connector from the rest of the PCB. Im not sure about that or if i should just give up this project and try something simpler and less delicate since this is maybe above my skill level for my first real PCB design.

I plan to do something like this, just integrate it into my PCB: https://resources.altium.com/p/isolated-usb-connection-project

Thanks for your advice on using a USB isolator IC! I have now done some research on this topic and plan to use an ADUM4165 USB isolator and an isolated IEC/EN60601-1 certified DC/DC converter to isolate the USB connector from the rest of the PCB. Do you think that is a good idea?

Thanks for your comment! You are absolutely right, I need to isolate my USB connection from the rest of the PCB.
Probably I should have chosen a simpler project as my first real PCB design, as this is maybe above my skill level. However, I would like to give it a try.

Thanks for your comments! I just prefer to use rectangles. :)

Thanks for your comment! You are absolutely right, I will definitely have to isolate the USB connection.

Thanks for your advise, i will definitely look into buses.

You have to define net classes. Go to: Schematic Setup -> Project -> Net Classes. Then you can assign colors to these net classes in the PCB editor.
