Proper termination, effective grounding, and a well-designed PCB layout are the key steps to ensuring that the signal integrity is maintained, and data can be transmitted without error. Always remember that small mistakes in signal transmission can cause big problems, so addressing these issues early can save a lot of time and frustration down the line.
