NEW PRODUCTS – 1.2″ 8×8 Matrix Square Pixels w/ and w/out Backpacks in Blue / Amber / Yellow / Pure Green / White

8x8 ultra

Make a scrolling sign, or a small video display with these 8×8 square gridded LED matrices. Only 1.2″ on a side, these are quite visible but not so large that they wont plug into a breadboard! 64 LEDs are contained inside the plastic body, in an 8×8 matrix. There are 16 pins on the side, 8 on each, with 0.1″ spacing so you can easily plug it into a breadboard with one row on each side for wiring it up.

Since the display is in a grid, you’ll need to 1:8 multiplex control it. We suggest either using a 74HC595 and TPIC6B595 (using the 74HC’ to control the 8 anodes at once and then using the TPIC’ to drive one cathode at a time) or just using a single MAX7219 which will do the multiplexing work for you.

The Arduino playground has a nice set of tutorials introducing the MAX7219 and 8×8 LED matrices.

We also have them with backpacks (as seen above)! Wouldn’t it be awesome if you could control a matrix without tons of wiring? That’s where these lovely LED matrix backpacks come in. We have them in three flavors – a mini 0.7″ 8×8, a small 1.2″ 8×8 and a 4-digit 0.56″ 7-segment. They work perfectly with the matrices we stock in the Adafruit shop and make adding a bright little display trivial.

All in stock and shipping now!
