Display, elegantly, 012345678 or 9! Gaze, hypnotized, at ABCDEFGHIJKLM – well these can display the whole alphabet. You get the point. These are nice, bright 14-segment alphanumeric displays that can show letters and numbers in beautiful hues. They’re super bright and designed for viewing from distances up to 23 feet (7 meters) away. Digits have seven segments on a black surfaces and we give you a set of two alphanumeric displays in a pack so you can make a clock or a four letter word.
There are nine pins per side on these, so 18 pins total, with 0.1″ spacing so you can easily plug it into a breadboard with one row on each side for wiring it up. Note that these may not color-match our other 7-segment displays due to process-differences.
These products are just the two alphanumeric displays!

Digits have seven 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!
These products come with:
2 x Ultra-Bright Alphanumeric Displays – 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!
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.

have the BIG RED 1.2" high seven-segment LED displays… When I take a picture of a number displayed (with a digital camera) some of the segments are ‘greyed-out’… – my GUESS is that there are two LEDs in each segment (the amp draw is HUGE) and that they ‘alternate’
(probably 60 times a second (even though they are DC) – and the digital camera’s shutter catches the darn thing when some segments are un-lit because the digital camera has a really fast shutter-speed?
ANYONE got any idea what i can do to get better pictures? – if you want the image I can send it to you…
