Product description
Neopixel-compatible RGB LED ring with 21 individually addressable RGB LEDs. Each LED includes an integrated serial controller (WS2812B), allowing all LEDs to be controlled via a single data line. This enables precise color control from a single data line connected to a microcontroller. You can easily create advanced lighting patterns and smooth color transitions. The ring has a diameter of 58 mm and is suitable for projects such as indicators, visual effects, or decorative installations. The ring module can also be daisy-chained, allowing multiple modules to be connected in series on the same data line.
The LED ring can be used with all 21 LEDs, or it can easily be split into two rings plus a single LED. Connection is made via clearly labeled solder pads for power, ground, and data signal in/out.
When using microcontrollers with 3.3 V logic levels (e.g. Raspberry Pi, ESP32), a level shifter is recommended for reliable and stable operation.
