8X8X8 RGB LED Cube Shield

Introduction

8*8*8 RGB Led cube is one of the stunning RGB light cubic module designed by us,and poses the arduino compatible interface and use the SPI interface as the control interface. It has several color mode inside.

This shield is coming a kit as below, you need soldering the LEDs to a complete shield as the upper picture.

Features

• Dimensions: 120×100×90mm
• Net weight: 265g

Schematics

• 8x8x8led_cube_schematic

Usage

Below is a demo code to use 8*8*8 RGB Led cube with Arduino:
