This is the Green Adafruit 0.8" 8x16 LED Matrix FeatherWing Display Combo Pack! We Also have these combo packs in White, Blue, Red, Yellow, and Yellow-Green.
This kit combines two of our adorable miniature LED matrices with a FeatherWing driver board. Double them up for 128 total bright red LEDs.
Normally, wiring up 8x16 matrices would require a breath-taking 24 GPIO pins, which is way too many pins. That's where this lovely 16x8 LED matrix backpack PCB comes in. It contains a HT16K33 I2C LED matrix driver that does all the multiplexing work for you, and is controlled over the two I2C pins. It's easy to use, has a portable library that runs on any of our Feathers to turn on/off each LED.
The 16x8 backpack is also great for making scrolling displays or small video displays. In our example, we set it up to display small bitmap emoticons but you can also display text that moves - kind of like a sign in front of a miniature car dealership.
The board/chip uses 12C 7-bit address between 0x70-0x77, selectable with jumpers
