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. 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 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. 
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, 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.

Features:
I2C 8x8 LED matrix, very nice with LED matrix backpacks.
They have a built in clock so they multiplex the display.
This LED matrix are very nice with good build quality and great packaging.
