These great little displays can show any letter or number! This is a nice, bright alphanumeric display that shows letters and numbers in a beautiful red 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 we 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 the other LED backpacks we offer, 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!
This product comes with:
- 2 x Ultra-Bright Red Alphanumeric Display – 0.54″ Digit Height for 4 digits total
- 1 x Adafruit 14-segment LED Alphanumeric Backpack
- 1 x 5-pin header
A bit of soldering is required to attach the matrix onto the backpack but its very easy to do and only takes about 5 minutes. Of course, in classic Adafruit fashion, they also have a detailed tutorial showing you how to solder, wire and control the display. If you’ve been eying alphanumeric displays but hesitated because of the complexity, this is the solution you’ve been looking for!
Also available in Blue and Green!
