An 8×8 RGB LED dot matrix module with an integrated SPI backpack controller. Drives a full-colour LED matrix using just 3 digital pins (or hardware SPI), eliminating the complexity of directly driving 64 RGB LEDs. Supports up to 7 colours with a maximum 3×3 cascade configuration.

The module features a daisy-chainable design — connect multiple modules both vertically and horizontally to build larger RGB matrix screens. High-speed data transmission ensures smooth display refresh rates. Directly supports Arduino with an included library.
