The Adafruit 14-Segment LED Alphanumeric Backpack is a standalone I2C LED driver board that makes it easy to add a 4-character alphanumeric display to any project. Powered by the HT16K33 chip, it handles all LED multiplexing over I2C — just send commands and it lights up the right segments for you.
