I assume these are the same displays as your 1" 7-Segments that are actually 0.8" tall? And why did you use the 328P over the 32u4? I would have preferred if you used different firmwares instead of solder jumpers for the different modes, and breaking out more pins would have been awesome.
But really, those are just small things. Thank you for listening to our feedback and making these, they look great!
