Adafruit Small 1.2" 8x8 Bi-Color (Red/Green) Square LED Matrix

This compact 8x8 bi-color LED matrix display, measuring just 1.2 inches square, offers vibrant visuals in red, green, yellow, and even custom shades through rapid multiplexing. It fits conveniently on a breadboard thanks to its manageable size.

The display features 24 pins with a 0.1-inch spacing, making it easy to set up. Each grid contains two LEDs under diffused square lenses, creating a striking visual effect. To drive this grid, a 1:8 multiplexing method is used. For efficient control, consider utilizing two 74HC595 and TPIC6B595 chips or opt for the MAX7219, which handles the multiplexing for streamlined operation.

Ideal for crafting scrolling signs or vibrant video displays, its versatility shines in hobbyist projects and more technical applications. The Arduino playground offers comprehensive tutorials to help you get started with MAX7219 and similar LED matrices.
