Small 1.2" 8x8 Bright Square Pure Green LED Matrix + Backpack SF_Memory Cards The Alchitry Au features aWhat's better than a single LED? 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
