Circuit Boards

One tiny LED display choice that's in production although quite expensive is Avago. See http://www.mouser.com/Broadcom-Limited/O...?P=1z0zlfz or http://www.mouser.com/Broadcom-Limited/O...fzZ1yzugs8 . These are 5x7 dot matrix so you can do text or custom characters too, not just numerals. You feed the dot patterns to them with synchronous serial. They are stackable end to end or above and below.
