What#39;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 #39;multiplexed#39; - so to control all the seven-segment LEDs you need 14 pins. That#39;s a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there#39;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#39;t it be awesome if you could control a matrix without tons of wiring That#39;s where these adorable LED matrix backpacks come in. We have them in two flavors - a mini 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. The backpacks come with address-selection jumpers so you can connect up to four mini 8x8#39;s or eight 7-segments (or a combination, such as four mini 8x8#39;s and four 7-segments, etc) on a single I2C bus.
