## Description

Display, elegantly, 012345678 or 9! Gaze, hypnotized, at ABCDEFGHIJKLM - well it can display the whole alphabet. You get the point. This is a nice, bright alphanumeric display that shows letters and numbers in a beautiful yellow-green hue. It's super bright and designed for viewing from distances up to 23 feet (7 meters) away. Digits have seven white segments on a black surface and Adafruit give you a set of two alphanumeric displays as well as a driver board so you can make a clock or a four letter word.

Like Adafruit's other LED backpacks, these are end-to-end stackable and by soldering the address jumpers on the back you can have up to 8 backpacks all sharing the same two I2C wires!

- 1 x Adafruit 14-segment LED Alphanumeric Backpack
- 1 x 5-pin header
