What'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

Here 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 lovely LED matrix backpacks come in. br / table class t info tbody tr th class title colspan 2 General /th /tr tr td class attr Brand /td td Keyestudio /td /tr tr td class attr Model /td td N/A /td /tr tr td

Matrices like these are 39 multiplexed 39 - so to control 64 LEDs you need 16 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

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

They use constant-current drivers for ultra-bright, consistent color, 1/16 step display dimming, all via a simple I2C interface
