Is there a serial port on the cm4 that I can bring out? I got the version without the modem so I have a blank plate where I can put a connector.
Or would I be better off wiring an extra USB device inside?
Just trying to clean up the outside when I’m using it.

Looks like both of the onboard ports are in use, I thought it had a third port.
both? specs say there are up tio 5:
• 28 × GPIO supporting either 1.8V or 3.3V signalling and peripheral options:
Up to 5 × UART
Also people on forum says it at least UART2 should work: https://forums.raspberrypi.com/viewtopic.php?t=344365
