1 piece RGB LED Full Color Drive 4 Foot Light Module Development Board CJMCU2812B WS2812B Product highlights Full color RGB lighting module using WS2812B integrated driver for perpixel color control. Designed as a development board and dropin 4 foot light module for prototyping and installation. Compact PCB assembly with SMD RGB LEDs and driver ICs, ready for direct connection to a controller. Singlewire digital control simplifies wiring and allows chaining multiple modules for larger installations. Provides precise color mixing and individual pixel control for dynamic lighting effects. Why choose this module Simplifies development and installation by combining LEDs and WS2812B drivers on a single 4 foot board. Reduces wiring complexity with a standard serial data interface, letting you focus on patterns and control logic. Enables finegrained control of color and brightness for custom lighting, signage, and interactive projects. Key attributes Function: Addressable full color RGB lighting with perpixel control driven by WS2812B protocol. Compatibility: Works with controllers and libraries that support WS2812B style data signals. Size: 4 foot module form factor suitable for linear installations and prototyping. Material: SMD RGB LEDs mounted on a PCB development board for stable mechanical and electrical connections. Performance: Individual pixel addressing for precise color, animation, and brightness control. Typical applications Ambient and accent lighting for furniture, shelving, or display cases where a 4 foot linear module fits directly. Custom signage and retail displays requiring dynamic color patterns and simple chaining of multiple boards. Prototyping and interactive installations that combine sensors or controllers to drive pixellevel effects. What is included One 4 foot RGB LED full color drive development board CJMCU2812B WS2812B.
