Lots of LEDs! A fun way to make a small display is to use an\u003cspan\u003e \u003c\/span\u003e8x8 matrix\u003cspan\u003e \u003c\/span\u003eor a\u003cspan\u003e \u003c\/span\u003e4-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\u003cspan\u003e \u003c\/span\u003edriver chips like the MAX7219that 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 adorable LED matrix backpacks come in. We have them in two flavors -\u003cspan\u003e \u003c\/span\u003ea mini 8x8\u003cspan\u003e \u003c\/span\u003eand a\u003cspan\u003e \u003c\/span\u003e4-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.\u003cbr\u003e\u003cbr\u003eThe 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 (\u003cstrong\u003ethe images above are photographed at the dimmest setting to avoid overloading our camera!\u003c\/strong\u003e), 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's or eight 7-segments (or a combination, such as four mini 8x8's and four 7-segments, etc) on a single I2C bus.\u003cbr\u003e\u003cbr\u003eThe product kit comes with:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA fully tested and assembled LED backpack\u003c\/li\u003e\n\u003cli\u003eUltra-bright 8x8 white matrix\u003c\/li\u003e\n\u003cli\u003e4-pin header\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA bit of soldering is required to attach the matrix onto the backpack but its very easy to do and only takes about 5 minutes.\u003cbr\u003e\u003cbr\u003eOf course, in classic Adafruit fashion,\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"http:\/\/learn.adafruit.com\/adafruit-led-backpack\/\"\u003ewe also have a detailed tutorial showing you how to solder, wire and control the display\u003c\/a\u003e.
