I've added an ELITE 3.5 lcd zumspot radio to my collection. it's up and running perfectly.
What I want to know is what are the external connections for?
next to the pwr connector are 2 usb (TYPE?) and next to that is what
looks like a connection for a speaker? as well as the USB and USB 3.0 connections.
can't seem to find any docs pertaining to them.
anyone know what they all are for?

It isn't quite clear where you see these ports.

Based upon Zum's website, the elite 3.5 is a complete package with LCD and R-Pi 4. Presuming your mystery ports are on the R-Pi 4, then looking up R-Pi 4 documentation would be the proper step.

FYI: The R-Pi 4 has TWO (mini) HDMI (video) ports between a USB-C power input and a stereo audio jack. There are two USB-3 and two USB-2 ports on the end, next to the RJ-45 Ethernet
