LED Ring RGB WS2812-12 47mm for Raspberry Pi DFRobot DFR0888-12

The LED Ring RGB WS2812-12 47mm is a compact addressable RGB ring module with 12 individually controllable WS2812 LEDs arranged in a 47 mm diameter. Designed for use with Raspberry Pi and compatible microcontrollers, the module uses the WS2812 protocol to deliver full-color pixels over a single data line. Its small form factor and integrated LEDs make it suitable for status indicators, decorative lighting, feedback displays, and compact lighting effects in DIY electronics and maker projects.

Advantages

The WS2812-12 ring combines individually addressable LEDs with a standardized single-wire control protocol, enabling precise color and brightness control for each pixel. The 47 mm diameter provides a compact footprint that fits into enclosures or on prototyping boards, while the integrated LEDs reduce the need for external drivers. Compatibility with Raspberry Pi and common microcontrollers simplifies integration into existing projects and libraries, and the RGB capability allows a wide spectrum of colors and smooth animations.

Suitable for

• Visual status indicators and notifications on embedded systems
• Decorative and accent lighting in small enclosures
• Light effects and animations in maker and education projects
• Prototyping LED sequences and pixel-level control experiments

Key specifications

• LED type: WS2812 addressable RGB LEDs
• Number of LEDs: 12 individually controllable pixels
• Diameter: 47 mm
• Control interface: single data line (WS2812 protocol)
• Operating voltage: compatible with typical 5 V logic systems (verify controller requirements)
• Mounting: compact ring form factor suitable for panel or prototype mounting

How to use

Connect the ring to a compatible controller such as a Raspberry Pi or other microcontroller, providing appropriate power and ground connections and a single data line to the input pin. Use a library or driver that supports WS2812 LEDs to address individual pixels, set colors, and create effects. Ensure power supply can meet current demands when multiple LEDs are at high brightness, and place a suitable level shifter if your controller’s data voltage differs from the ring’s recommended signal voltage. Follow standard wiring practices to prevent reverse polarity and avoid exposing the module to moisture.

Usage recommendations

For reliable operation, use a stable 5 V power source sized for peak current (approximately 60 mA per LED at full white), add a decoupling capacitor near the power input, and include a small series resistor on the data line to reduce signal ringing. When integrating with Raspberry Pi, use proven WS2812 libraries and consider level shifting the data signal to match the LED ring’s logic level. Avoid driving all LEDs at maximum brightness for extended periods to reduce heat and power consumption.
