WS2812 64 Bit RGB LED Matrix Module

WS2812 64 Bit RGB LED Matrix Module is a versatile and high-density display solution designed for creating vibrant, full-color visual effects in embedded projects. This 8×8 grid integrates 64 individually addressable WS2812B LEDs, which allow you to control the color and brightness of every single pixel using just one data pin from a microcontroller. Consequently, it eliminates the complex wiring typically associated with traditional LED arrays. Utilizing the built-in control circuit and RGB chip, each LED provides 256 levels of brightness and 16,777,216 possible colors. Furthermore, the module supports daisy-chaining, which enables you to expand your display by connecting multiple matrices together. Therefore, you can easily develop complex scrolling text, animations, and decorative lighting systems for your next DIY electronics design.

Key Features:

• Individually Addressable: Every one of the 64 LEDs operates independently, giving you total creative control over the entire 8×8 matrix grid.
• Single-Wire Communication: The module uses a high-speed, one-wire protocol, which significantly reduces the number of GPIO pins required on your host controller.
• 24-Bit Color Depth: Each pixel features internal 8-bit processing for each color channel, resulting in a rich palette of over 16 million distinct colors.
• Chainable Design: Built-in “Data Out” pins allow you to link several modules in a series to create larger, seamless displays.
• Integrated Control Circuit: The WS2812B IC resides inside the 5050 LED package, ensuring a clean PCB layout and high reliability.
