What it is
The WS2812 16-LED RGB Ring is an addressable RGB LED module built around WS2812 LEDs in a circular layout for animations, status indicators, clocks, wearables, and compact lighting effects. It uses a single-wire data interface instead of I2C, SPI, or UART, making it a popular choice for Arduino, Raspberry Pi, and ESP32 projects; for exact pinout and datasheet-style details, check the module silkscreen and listing photos.
Pins
Refer to the silkscreen labels on the board/module and the listing photos for exact pin names. WS2812 rings commonly use power, ground, and a data connection, but confirm the printed pinout on your specific module revision before wiring.

Frequently Asked Questions
How do I connect the WS2812 16-LED RGB Ring to Arduino, Raspberry Pi, or ESP32?
Connect power and ground plus one data pin, then use a WS2812-compatible library or code example on your controller. Check the board silkscreen and listing photos for the exact pinout on your module revision before wiring.
Does the WS2812 16-LED RGB Ring use I2C, SPI, or UART?
No. This RGB ring uses a single-wire addressable LED data interface, not I2C, SPI, or UART.
Can each LED on the WS2812 ring be controlled individually?
Yes. Each of the 16 WS2812 LEDs is individually addressable, so you can set different RGB colors and animation patterns for each LED.
What voltage does the WS2812 16-LED RGB Ring require?
The provided product description does not list a specific operating voltage. Verify the datasheet, module markings, or listing photos for your exact board revision before applying power.
