Small 8×8 Dot Matrix Ultra Bright – White [Discontinued]
This small 8 x 8 (64 LED) dot matrix is only 1.25″ (32mm) square, and ready to display any scrolling text, graphs, clock display, counter or signs you can think of!
The ultra-bright LEDs are very visible, and the units are small enough to plug into a breadboard! The 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.
This dot matrix requires an IC to run, and the display is in a grid so you’ll need a 1:8 multiplex to control it. You can run it with a MAX7219 which does the multiplexing for you.
