The folks at Adafruit 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 - they work perfectly with the matrices Adafruit stock 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, 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\n\u003cul\u003e\n\u003cli\u003eA fully tested and assembled 1.2\" LED backpack\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.adafruit.com\/products\/1821\"\u003e1.2\" 8x8 Matrix Square Pixel White \/ w\/backpack\u003c\/a\u003e\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=\"https:\/\/learn.adafruit.com\/adafruit-led-backpack\/\"\u003ethey also have a detailed tutorial showing you how to solder, wire and control the display\u003c\/a\u003e.
