How to Implement Scrolling Display for MIDI Inputs on Arduino Opta with SSD1306 OLED?
Considering diving into the world of 4-layer boards for this MIDI processing/pass-through application, meaning that any signals that I pass will transmit at 31,250 baud. I don't think the board will be that difficult to design circuitry-wise, but what is the prevailing idea for how to stack the layers in such a board?
Thinking maybe GND, Signals, GND, Power would provide the best noise immunity and make it really easy to access the power that I need. OTOH, having multiple GND planes might also mean GND loops from what I understand... though my understanding of said loops is rather vague. Guess I'd need to pass some vias though the GND sandwitch.
Anyway, open to ideas/standard practice here.
