Ardrando – Arduino based random quantized sequence generator

I found this module on reddit and really liked the youtube video I can’t find right now but there is a github

This is the original schematic and my layout as well as the pinouts needed.

How to make this any better? So far I had no problems with the build BUT there some output and input protection missing imo. Maybe attenuate too hot signals going in? Idk. But have fun with it!
