You can use our great library for the backpacks and get up and running in less than half an hour. If you've been interested in matrix displays but were put off by the complexity, this is the perfect solution! Like our other LED backpacks, these are stackable from end to end. By soldering the address jumpers on the back, you can have up to 8 backpacks sharing the same two I2C wires. It comes with a fully tested and assembled LED backpack and some headers. A little light soldering is needed to attach the headers and, of course, the display. Note that a 1.2' 8x8 matrix display is not included, but we have many options in the store. We only guarantee compatibility with the ones we stock. Other 1.2' square 8x8 displays may not work.
