Lots of LEDs! 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 mini 0.7\" 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.\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. 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.\u003cbr\u003e\u003cbr\u003eThe product kit comes with:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eA fully tested and assembled 1.2\" LED backpack\u003c\/li\u003e\n\u003cli\u003e1.2\" 8x8 Matrix Square Pixel in Amber\u003c\/li\u003e\n\u003cli\u003e4-pin header\u003c\/li\u003e\n\u003c\/ul\u003e\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, 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!\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cp\u003eDatasheets, Fritzing object, EagleCAD PCB files and more in the tutorial!\u003cbr\u003e\u003cbr\u003eMatrix Dimensions:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e31mm x 312mm x 7mm \/ 1.2\" x 1.2\" x 0.3\"\u003c\/li\u003e\n\u003cli\u003eHeight without Pins: 7mm \/ 0.3\"\u003c\/li\u003e\n\u003cli\u003eWeight: 7.65g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eBackpack Dimensions:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e41mm x 33mm x 2mm \/ 1.6\" x 1.3\" x 0.08\"\u003c\/li\u003e\n\u003cli\u003eWeight: 5.2g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":44930773352537,"sku":"jnu1789672693884","price":8.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/5289\/5833\/files\/small-12-8x8-ultra-bright-square-amber-led-matrix-backpack-discontinued_1.jpg?v=1789672698","url":"https:\/\/gymflexfit.shop\/products\/small-12-8x8-ultra-bright-square-amber-led-matrix-backpack-discontinued","provider":"My Store","version":"1.0","type":"link"}
