A tribute to one of the greatest players ever, the BDN9 is a fun little 3x3 macropad that lets you try out a couple of rotary encoders as well. What can you do with rotary encoders? That's for you to figure out! Use it as up/down, page up/down, volume control, or whatever, get creative. Go win a Super Bowl with it or something.

Also, this build doesn't require any diodes, simplifying the build.
