16x8 1.2" LED Matrix + Backpack -Ultra Bright Square Yellow LEDs SF_Ethernet labeled A0 through A5What's better than a single LED? Lots of LEDs! And what's better than lots of LEDs? TWO TIMES AS MANY LEDS!!! With the 16x8 LED Matrix Backpack we've doubled your project's matrix capacity by making it super easy to get two separate 8x8 matrices onto one handy board! Matrices like these are 'multiplexed' so to control 64 LEDs you need 16 pins and to control 128 LEDs, you'd need 24 pins. That's a lot of pins, and there are driver chips like the MAX7219
