Description

Display, elegantly, 012345678 or 9! Gaze, hypnotized, at ABCDEFGHIJKLM - well it can display the

whole alphabet. You get the point.

This is the Green Adafruit 0.54" Dual Alphanumeric FeatherWing Display Combo Pack! We also have

these combo packs in Blue, Red, White, Yellow-Green, and Yellow.

This is a nice, bright alphanumeric display that shows letters and numbers in a beautiful hue. It's

super bright and designed for viewing from distances up to 23 feet (7 meters) away. Each of the digit

sets have 14 segments on a dark background and we give you a set of two alphanumeric displays as

well as a Featherwing driver board so you can make a clock or a four letter word.

Works with any and all Feathers!

14-Segment Matrices like these are 'multiplexed' - so to control all the fourteen-segment LEDs you need 18

pins. That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but

there's a lot of wiring to set up and they take up a ton of space. Wouldn't it be awesome if you could control a

matrix without tons of wiring? That's where these Alphanumeric LED Matrix FeatherWings come in, they

make it really easy to add a 4-digit alphanumeric display with decimal points.

The LEDs themselves do not connect to the Feather. Instead, a matrix driver chip (HT16K33) does the

multiplexing for you. The Feather simply sends i2c commands to the chip to tell it what LEDs to light

up and it is handled for you. This takes a lot of the work and pin-requirements off the Feather. Since

it uses only I2C for control, it works with any Feather and can share the I2C pins for other sensors or

displays.

The product kit comes with:

A fully tested and assembled Adafruit 4-Digit 14-Segment Alphanumeric Display FeatherWing

0.54" Ultra-bright dual alphanumeric green display - 2 pack

Two 16-pin headers

Of course, in classic Adafruit fashion, we also have a detailed tutorial showing you how to solder, wire

and control the display. We even wrote a very nice library for the backpacks so you can get running in

under half an hour, displaying images on the matrix or numbers on the 14-segment. If you've been

eyeing matrix displays but hesitated because of the complexity, his is the solution you've been

looking for!
