Four digits of one inch 16 segment alphanumeric goodness!  With TLC5926 drivers for each digit, there is no need to worry about dim displays due to mulitiplexing here.  All LEDs are addressable except the dot LEDs.  The LED digits themselves are 25.4mm high (1 inch) high.

This display is pre-built and requires no construction, except for adding breakaway headers or soldering wiring directly to the board.

Displays can be daisy chained to create displays as large as you like!
