Description
7Semi-WS2812B Digital RGB LED Module
The 7Semi WS2812B Digital RGB LED Module is a compact addressable RGB LED unit that integrates an RGB LED and a built-in driver IC in a single 5050 package. It allows full control of color and brightness using just one data line, making it ideal for creating dynamic lighting effects. Multiple modules can be daisy-chained to form LED strips, rings, or matrices, suitable for decorative, embedded, and robotic applications.
