HT16K33 board for 11x7 LED matrix

I recently bought a cool 11x7 matrix, that is just great to display 4 3x5 digits and I want to control it with the well supported HT16K33 - so here's a not so beautiful and highly convoluted board for that.

Aww, you beat me to it. I actually designed one this morning, after reading your comment, but when I finished I realized I put the matrix on the wrong side of the board. I didn't have the heart to start over. But I will get to it, sooner or later. By the way, the HT16K33 can also handle keys -- maybe it would make sense to put a couple of buttons on the breakout too?

would be cool to have it as a wemos d1 shield though. What's your plan, shield or basic board?

Are you sure? yes | no

I think I will make a shield, you can always use it as a general purpose board after all, just ignore all the extra pins.
