Hey everyone,
Doing my first pcb layout and i've got a few questions.
The circuit employs a microcontroller to control some relays which, in turn, control some audio circuits.
The microcontroller is a standalone unit that is not part of the board that i'm laying out.
So basically, i am using some digital i/o pins from the MCU to connect to my board. These signals drive some transistors which drive the relays (which ARE on my board).
Okay. Thats the background. I am wondering if i need to take any particular precautions when laying out such a circuit. That is, should i keep all the signals from the controller on one layer? Is it okay that audio traces run near controller traces? Is it okay that audio traces cross controller traces that are on a different layer? Grounding issues? etc, etc...
In essence, what do i need to watch out for?
Any tips or advice would be GREATLY appreciated.
