i have opened alot of things loike gameboys phones and controllers, and all the circuit boards look exactly the same. so what is it that makes them work differently? what makes the circuit board in my phone work differently from the one in my game boy?

i know there all the resistors and transistors but how do i tell what they are and what else is on there. also can i use just an random circuit board for anything or are they made special for certain things.

I am an Electrical Engineering student. I want to design PCB. So I need any simple circuit website, so from there i will pick the circuit…
