7Semi 8-LED Addressable RGB Stick Module, 5V, WS2812B-V5 Individually Controllable LEDs for Arduino, ESP32, and Raspberry Pi
The 7Semi 8-LED Addressable RGB Stick Module has eight WS2812B-V5 LEDs soldered in a single line on a compact PCB. Each LED combines the control circuit and the RGB chip in a 5050-size package, forming a complete addressable pixel. Every pixel supports 256 brightness levels per colour, which gives 16,777,216 colours in total, with a scan frequency of 2 kHz. The high refresh rate helps avoid visible flicker when the lighting is captured on a video camera.
The module needs only one data line, so it is simple to connect to Arduino, ESP32, Raspberry Pi, and other microcontrollers. The control circuit and the LED share a single 5 V power source. A built-in signal reshaping circuit rebuilds the waveform at each pixel, so signal distortion does not build up across a long chain. Modules can be cascaded through the DIN and DO ports, with a data rate of 800 Kbps. At a 30 fps refresh rate, a chain of 1024 or more pixels is supported. The colour consistency between pixels is high, which makes the module well-suited for decorative lighting, indicators, and display projects.
Key Features
- LED Type: 8 WS2812B-V5 addressable RGB LEDs in a 5050 package
