16x8 1.2" LED Matrix + Backpack-Ultra Bright Round Orange LEDs

With the 16x8 LED Matrix Backpack you double 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 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. That's where this lovely 16x8 LED matrix backpack comes in.

The backpack uses a HT16K33 driver chip that does all the heavy lifting for you.  This chip has a built in clock so they multiplex the display. It uses constant-current drivers for ultra-bright, consistent color (the images above are photographed at the dimmest setting to avoid overloading the camera!), 1/16 step display dimming, all via a simple I2C interface. Each matrix backpack comes with three address-selection jumpers so you can connect up to 8 x 1.2" 16x8's together on a single I2C bus.
