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 blue hue. It's super bright and designed for viewing from
distances up to 23 feet (7 meters) away. Digits have seven blue 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 our 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!
This product comes with:
2 x Ultra-Bright Blue 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, we 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!
