What it is
WS2812 24-Bit RGB LED Ring 90mm for Arduino, Raspberry Pi & ESP32 is a 90mm circular array of digitally controlled 24-bit full-color LEDs built around the WS2812 smart LED chipset. Each pixel is addressable over a single-wire serial data line for animated lighting, status indication, clocks, and visual effects. Unlike I2C, SPI, or UART modules, this ring uses the WS2812 LED protocol and is commonly used with Arduino, Raspberry Pi, and ESP32 projects.
Pins
Refer to the silkscreen labels on the board/module and the listing photos for exact pin names. WS2812 rings generally require power, ground, and a data connection, but use the printed pinout and a WS2812 datasheet for exact wiring and timing guidance.

Frequently Asked Questions
How do I connect a WS2812 LED ring to Arduino, Raspberry Pi, or ESP32?
Connect power, ground, and the data line according to the board silkscreen labels and your controller documentation. Check the listing photos and a WS2812 datasheet for exact pinout, timing, and voltage guidance before powering the ring.
Does this 90mm WS2812 LED ring use I2C, SPI, or UART?
No. This LED ring uses the WS2812 single-wire serial data protocol rather than I2C, SPI, or UART.
Is each LED on the WS2812 ring individually addressable?
Yes. The WS2812 smart LED chipset allows each pixel on the ring to be controlled for color changes, chases, and custom animation patterns.
What can I build with a 90mm WS2812 RGB LED ring?
Common uses include clocks, status indicators, music-reactive lighting, costume builds, robotics, art installations, and compact home automation displays.
Where can I find the pinout or datasheet for this WS2812 ring?
Use the board silkscreen and listing photos for exact pin names. For protocol details, timing, and software support, refer to a WS2812 datasheet and the library documentation for your Arduino, Raspberry Pi, or ESP32 platform.
