Description:

0.54" 4 bit digital LED display module I2C control For
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.
All you have to do is write data to it using the 2-pin I2C interface
