Small 1.2″ 8×8 Ultra Bright Square White LED Matrix + Backpack
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 two flavors – a a small 1.2″ 8×8 and a 4-digit 0.56″ 7-segment. They work perfectly with the Adafruit matrices we stock 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, 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″ 8×8’s together (or a combination, such as four 1.2″ 8×8’s and four 7-segments, etc) on a single I2C bus.
The product kit comes with:
- A fully tested and assembled 1.2″ LED backpack
- 1.2″ 8×8 Matrix Square Pixel White / w/backpack
- 4-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 have a detailed tutorial showing you how to solder, wire and control the display. They 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!
