Neat project! Are you willing to share the updated project files with the 3 separate layers?

I just received these a few days ago. What is the pinout to drive it?

Have a look at #DYPLED and tell me if the 4014 LED format fits your needs :-)

  Are you sure? yes | no

I am using 0802 LEDs

  Are you sure? yes | no

This is good to know :-) #PICTIL uses 0402 but no charlieplexing to reach higher speed.
Now I wonder how to do charlieplexing in TTL gates :-D

  Are you sure? yes | no

I am sorry, I lost source files, I need complete rework this display. You can try reorder this board  https://oshpark.com/shared_projects/eL6HGlbh I have not finished arduino code now :(
