What's better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8x8 matrix or a 4-digit 7-segment display. Matrices like these are 'multiplexed' - so to control 64 LEDs you need 16 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.Here at Adafruit we feel your pain! After all, wouldn't it be awesome if you could control a matrix without tons of wiring? That's where these lovely LED matrix backpacks come in. We have them in three flavors, a mini 0.7" 8x8, a small 1.2" 8x8, and a 4-digit 0.56" 7-segment. They work perfectly with the matrices we stock in the Adafruit shop and make adding a bright little display trivial.The matrices use a driver chip that does all the heavy lifting for you: They have a built-in clock so they multiplex the display. They use constant-current drivers for ultra-bright, consistent color (the images above are photographed at the dimmest setting to avoid overloading our camera!), 1/16 step display dimming, all via a simple I2C interface.These 1.2" matrix backpacks come with three address-selection jumpers so you can connect up to eight 1.2" 8x8's together (or a combination, such as four 1.2" 8x8's and four 7-segments, etc.) on a single I2C bus. The product kit includes: a fully tested and assembled 1.2" LED backpack, ultra-bright 1.2" 8x8 white matrix, and a 4-pin header.A bit of soldering is required to attach the matrix onto the backpack but it's 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. 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 7-segment.If you've been eying matrix displays but hesitated because of the complexity, this is the solution you've been looking for! https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2025-10-30 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2025-11-01 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2025-11-08 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2025-11-10 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2025-12-03 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2025-12-19 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-01-10 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-01-23 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-01-26 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-01-31 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-02-06 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-02-11 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-02-19 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-03-06 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-03-15 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-03-22 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-04-13 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-04-20 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-07-01 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-07-29 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-08-01 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-08-21 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-09-19 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-09-27 https://elecena.pl/product/29464586/adafruit-small-1-2-8x8-ultra-bright-white-led-matrix-backpack 2026-10-10
