I got a MAX 9814 but quickly realized the output is analog and not digital. I found that I could get an Arduino Nano/Micro and connect it to my Pi via a USB to USB-micro cable but I wonder if there's something more compact or simpler that I can do?
To make this question deterministic how would you go about solving this problem? I come from a background of not knowing about how to convert the signals but can solder just fine.
