In the spirit of the matrix sanitizer, here's a similar board that solves a slightly different problem: those bi-color LED matrices that have three rows of pins are impossible to insert into a breadboard. So we need something to make it two rows of pins.

This board does that for you. You can order it from @oshpark: https://oshpark.com/shared_projects/iOwHMYcW

I'm particularly happy that I managed to make it one-layer and symmetric.
