NeoPixel Ring - 16 x 5050 RGBW LEDs w/ Integrated Drivers - Natural White - ~4500K

Nav>

Looking for something better than ordinary RGB LEDs? These smart RGB+White LEDs are the answer! These NeoPixel rings feature 4 LEDs (red, green, blue, and white) for outstanding lighting effects. Imagine the beautiful circular patterns they can create!

This is the 16 - LED RGBW NeoPixel Ring in a lovely Natural White color. We also have a wide variety of other NeoPixel rings in our store for you to explore.

16 ultra - bright smart LED NeoPixels are arranged in a circle with an outer diameter of 1.75 inches (44.5mm). These rings are chainable - simply connect the output pin of one to the input pin of another. You can control multiple rings with just one microcontroller pin! Each LED is individually addressable thanks to the built - in driver chip. With a ~18mA constant current drive, the color remains consistent even when the voltage changes, and there's no need for external choke resistors, making the design sleek. Power it with 5VDC and you're all set for amazing lighting displays.

The NeoPixel is unique. One half is the familiar RGB part, and the other half is a white LED with a yellow phosphor. When unlit, it looks like an egg yolk. But when lit, it's incredibly bright! You can control it with 8 - bit PWM per channel (32 - bit color overall), perfect for adding colorful and white dots to your projects.

NeoPixel LEDs use an 800 KHz protocol, which requires specific timing. Their PWM rate is ~400 Hz, which works well but might be noticeable if the LED is moving. In contrast, DotStars have a 20 KHz PWM rate, offering smoother blending. We recommend DotStars if possible.

These 5050 - sized NeoPixel LEDs have an embedded microcontroller inside. You can precisely set the brightness and color of each R/G/B/W with 8 - bit PWM precision. They're controlled by shift - registers and only need 1 digital output pin for data transmission. Once you set the color, the LEDs will keep PWMing on their own.

We have a great tutorial that shows wiring, power usage calculations, and example code for using NeoPixels. Note that you'll need a NeoPixel library with RGBW support, which isn't always available. Our Adafruit NeoPixel library supports RGBW, but if you use other libraries, you might need to do some tweaking.

Our detailed NeoPixel Uberguide has all the information you need to use NeoPixels in any shape and size, including ready - to - go libraries and example code for various Arduino models.

Comes as a single ring with 16 individually addressable RGBW LEDs, already assembled and tested.

Using the NeoPixel Ring is easy. First, power it with 5VDC. Then, connect the rings together if you want to use multiple ones by linking the output pin of one to the input pin of another. You can control all the connected rings with just one microcontroller pin. To set the color and brightness of each LED, use a NeoPixel library with RGBW support. Our Adafruit NeoPixel library works great for this. If you're using a different library, you might need to make some adjustments. When wiring, make sure to follow the tutorial we provide for proper power usage and connections. As for maintenance, keep the ring away from water and excessive heat. If you're not using it for a long time, store it in a dry and cool place. Remember, these LEDs are very bright, so don't look directly at them for too long to avoid eye discomfort.
