Hi all,
I am a student struggling with a simple circuit for a self project. I have an edge connector mounted on a backplane PCB. Another PCB then is inserted into the connector mounted on the first board. Essentially, I would like to create a circuit that turns on an LED when the board is inserted into the connector (a "plugged in" indicator). A 3.3V trace is connected between the two boards when the board is inserted.
So my (very simple) circuits question is how can I create a circuit that turns on an LED when the 3.3V line is connected upon insertion? I am not too concerned with individual values of any resistors or mosfets (I can find this out on my own). Just was wondering if anyone is familiar with what is used in consumer products to indicate via LED when something is plugged in.
Thank you for any suggestions!
