Hello.

I get lots of these gold finger boards (ethernet boards) that have boxes that have boxes that look similar like Dallas, RTC RTK, real time clocks but lack the markings that say so. I don't see any pictures of clocks. Just wanted to ask here before sending.


Could someone please look at my photos? I've circled the suspicious boxes.

Thank you so much.

Nope, that's a signal transformer.

It has a small transformer built into an IC like package

Thanks for the fast reply! Are these types of signal transformers safe to leave on?
