Main function: This module is designed to realize running light effects. LEDs can light up, turn off, or change color in a sequence, making it suitable for decorative lighting, electronic displays, and creative electronic projects. Easy microcontroller integration: The module uses multiple pins for power, ground, and control, enabling straightforward connections to microcontrollers and simple LED control. RGB lighting capability: Built with 5050 fullcolor RGB LEDs, capable of emitting red, green, blue, and mixed colors to produce a wide range of color effects. Neat, compact layout: The LEDs are integrated on a blue circuit board, offering a clean, compact, and organized setup for electronic projects. Why you need it: Create visually engaging running light patterns without complex wiring. Achieve colorful lighting effects through RGB color mixing. Easily interface with common microcontrollers for prototyping and projects. Key attributes: LED type: 5050 RGB Board color: blue PCB Interface: multipin for power, ground, and control Performance: supports colorchanging sequences and lighting effects 23 practical use scenarios: Decorative lighting and signage for home decor, events, or displays, using running light sequences for attentiongrabbing visuals. DIY electronics and hobby projects, especially for experiments with microcontrollers (Arduino, etc.) to implement LED control and color effects. Creative electronic installations or smallscale stage lighting setups that require colorful, programmable LED sequences. Compatibility and use notes: Designed to connect easily to microcontrollers via dedicated power, ground, and control pins. Suitable for projects that require RGB color mixing and sequential lighting effects on a blue PCB substrate.
