What's cooler than a single LED? A whole bunch of them! And even better, double the number of LEDs! With our 16x8 LED Matrix Backpack, we've made it a breeze to fit two 8x8 matrices on one convenient board, doubling your project's matrix capacity. These matrices are multiplexed, which usually means a lot of pins to control them. But our backpack uses a HT16K33 driver chip to handle all the hard work. It has a built - in clock, uses constant - current drivers for super - bright and consistent color, and offers 1/16 step display dimming through a simple I2C interface. You can connect up to 8 of these 1.2' 16x8 units on a single I2C bus. This kit includes a fully tested and assembled 16x8 1.2' LED Backpack, 2 ultra - bright square 8x8 blue matrices, and a 4 - pin header. A little soldering is needed to attach the matrices to the backpack, but it's quick and easy, taking only about 10 minutes. We also have a detailed tutorial and a great library to get you up and running in under half an hour. It's perfect for scrolling or small video displays, like a sign at a mini car dealership.
Using this 16x8 LED matrix with backpack is a piece of cake. First, you'll need to do a bit of soldering to attach the two 8x8 blue matrices to the backpack. It's easy and only takes around 10 minutes. After that, you can connect it using the 4 - pin header. The backpack uses a simple I2C interface, so wiring it up to your project is straightforward. We've provided a detailed tutorial to show you how to solder, wire, and control the display. And there's a great library that can help you get started in under half an hour. You can use it to display images on the matrix or numbers on the 7 - segment. For scrolling or small video displays, just set it up like our example where words flow from one matrix to the other. As for maintenance, keep it in a dry place and avoid physical damage. The HT16K33 driver chip does a great job of keeping the display bright and consistent, but if you notice any issues, refer to our tutorial for troubleshooting.
