There are some reasons Electrical Engineering is a thing. When you open the datasheet for a chip, all the cool numbers in nice tables are not just there to be pretty, but because they are useful to design a circuit to put the chip in... And then you have your classic engineering subjects applied to electrical circuit constructs, like filtering, stability of feedback loops, etc. In the end you can design simple/medium-complexity digital electronics PCB with some common knowledge on PSUs, digital interfaces (including layout/return-current/impedance control) with the right tools, but non-trivial analog I would not even bother, I leave it to people with a real training in this field.
