Cool Components 8 LED WS2812 RGB Pre-soldered 32mm Ring

The Cool Components 8 LED WS2812 RGB Pre-soldered Ring is a compact, ready-to-use lighting module perfect for adding vibrant, programmable colour to your projects. This circular PCB ring features eight high-intensity WS2812B 5050 RGB LEDs, each with an integrated driver chip, allowing for individual pixel control from a single data line.

The module arrives with four connections pre-soldered: V+, GND, DATA IN, and DATA OUT. This eliminates the need for delicate soldering work, making it ideal for beginners, rapid prototyping, and projects where a clean finish is desired. The single-wire control protocol is fully compatible with the popular NeoPixel library, simplifying programming for stunning lighting effects, animations, and colour sequences.

A key advantage of this design is its daisy-chaining capability. The DATA OUT connection allows you to link multiple rings or other compatible WS2812 devices in a series, all controlled from a single microcontroller output. This makes it perfect for use with controllers that have a limited number of I/O pins, enabling complex displays without wiring complexity.
