Description:

This version of the LED backpack is designed for two dual 14-segment "Alphanumeric" displays.
These 14-segment displays normally require 18 pins (4 'characters' and 14 total segments each) .
This backpack solves the annoyance of using 18 pins or a bunch of chips by having an I2C constant-current matrix controller sit neatly on the back of the PCB.
The controller chip takes care of everything, drawing all the LEDs in the background.
