24-LED RGBW Neopixel Ring with Integrated Drivers and 6000K Cool White Light

Description

Introducing the 24 LED RGBW NeoPixel Ring in Cool White – a powerful and flexible lighting solution that adds stunning RGB and white lighting effects to your projects. With a perfect combination of vibrant colors and bright white, this NeoPixel ring will elevate your creative endeavors.

• 24 Ultra-Bright RGBW LEDs: This NeoPixel Ring features 24 individually addressable LEDs in a perfect circular arrangement, offering rich colors and brilliant white light.
• Cool White Version: The ring includes a white LED with a yellow phosphor, which provides a crisp cool white light that adds brightness and clarity to your design.
• Chainable Design: You can connect the output pin of one ring to the input pin of another, allowing you to chain multiple NeoPixel rings together. Control all of them with a single microcontroller pin, making it easy to expand your setup.
• Compact and Slim Design: With an outer diameter of 2.58″ (65.5mm), the ring’s slim design is ideal for use in various applications, from decorative lighting to creative displays.
• Constant Current Drive: Each LED features an 18mA constant current driver, ensuring consistent brightness and color, even when the voltage fluctuates. No external resistors are needed, keeping the design clean and efficient.
• 32-bit Color Control: The ring is capable of 32-bit color control (8-bit PWM per R/G/B/W channel), allowing you to create a wide range of lighting effects and colors. Whether you’re aiming for solid colors or complex animations, the possibilities are endless.
• Power Requirements: Simply power the ring with 5VDC (4-7V works) to bring it to life with vibrant colors and bright lighting effects.
• Timing-Sensitive Protocol: NeoPixel rings use an 800 KHz data protocol, which requires specific timing. For smooth operation, it is recommended to use a real-time microcontroller like an Arduino, as the timing protocol is highly sensitive.
• PWM Rate: The PWM rate of ~400 Hz works well for static displays, but if you’re moving the LEDs, you may notice some flickering. For smoother transitions, consider using DotStars, which offer a 20 KHz PWM rate for smoother animations.
• Easy to Control: With built-in shift-registers, you only need one digital output pin to control the entire ring. Once the color is set, the LEDs handle the PWM internally, so no further communication is needed.
• Pre-assembled and Tested: This NeoPixel Ring comes fully assembled and tested, so it’s ready to use right out of the box.
• Tutorials and Resources: We provide extensive tutorials covering wiring, power calculations, example code, and more to help you get started. Please note that you will need a NeoPixel library that supports RGBW to use this ring, as traditional RGB libraries will cause unexpected results.
