- It is designed to realize running light effects, where LEDs light up, turn off, or change color in programmed sequences. It is commonly used in decorative lighting, electronic displays, and creative electronics projects. - Uses 5050 RGB LEDs, capable of emitting multiple colors. Color effects are produced by mixing the red, green and blue channels. - The module has multiple pins for power, ground and control, enabling easy connection to microcontrollers and LED control. - The circuit board is clearly labeled with LED model information and related data to help quick identification and straightforward operation during use and debugging. - Use scenarios: 1) Decorative signs, ambient lighting, and displays that require running-light or color-changing effects. 2) Creative electronics projects or small displays that leverage RGB color mixing for dynamic lighting. 3) DIY prototypes and microcontroller projects that need easy LED control and rapid testing.
