Product Information
- This version of the LED backpack is designed for these big bright 7-segment displays.
- These 7-segment displays normally require 13 pins (5 'characters' and 8 total segments each) This backpack solves the annoyance of using 13 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.
