Description

You will chirp with delight when you see how easy it is to make your very own 8x16 LED matrix display for any Feather. This kit combines two of our adorable miniature LED matrices with a FeatherWing driver board. At 0.8" square these little 8x8 matrices have got everything a big LED matrix has but bite sized! Double them up for 128 total bright LEDs.

These are theAdafruit 0.8" 8x16 LED Matrix FeatherWing Display Combo Packs! We have these combo packs inWhiteBlueGreenRedYellow andYellow-Green.

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.

This kit comes with:

A bit of soldering is required to attach the two matrices onto the FeatherWing but its very easy to do and only takes about 15 minutes.
