NeoPixel Ring - 12 x 5050 RGBW LEDs w/ Integrated Drivers - Cool White - ~6000K

Smart RGB+White LEDs are even better than smart RGB LEDs! These NeoPixel rings feature 4 LEDs (red, green, blue, and white) for amazing lighting effects. This is the 12-LED RGBW NeoPixel Ring in Cool White. We have many other NeoPixel rings in our store. 12 ultra-bright smart LED NeoPixels form a circle with a 1.45' (37mm) outer diameter. They're chainable - just connect the output of one to the input of another. Control multiple rings with a single microcontroller pin. Each LED is addressable with an in - built driver chip. With ~18mA constant current drive, colors are consistent even with voltage changes, and no external choke resistors are needed for a slim design. Power it with 5VDC. The NeoPixel is divided, with one half being RGB and the other a white LED with yellow phosphor. They're incredibly bright and can be controlled with 8 - bit PWM per channel (32 - bit color overall). Great for adding colorful and white dots to your project. NeoPixel LEDs use an 800 KHz protocol. Their PWM rate is ~400 Hz, and compared to DotStars' 20 KHz, pixelation might be noticeable when the LED moves. We recommend DotStars if possible. NeoPixels are 5050 - sized LEDs with an embedded microcontroller. You can set R/G/B/W brightness and color precisely. They're controlled by shift - registers and only need 1 digital output pin. The PWM is built - in, so once you set the color, it keeps going. We have a tutorial on wiring, power usage, and example code. Note that you need a NeoPixel library with RGBW support, which isn't always available. Our Adafruit NeoPixel library supports RGBW. Our detailed NeoPixel Uberguide has all you need for using NeoPixels. It comes as a single ring with 12 individually addressable RGB LEDs, already assembled and tested.

Using the NeoPixel Ring is easy. First, power it with 5VDC. You can connect multiple rings by linking the output pin of one to the input pin of another and control them all with a single microcontroller pin. When setting the colors and brightness, you'll need a NeoPixel library with RGBW support. Our Adafruit library works great, but if you use another one, you might need to do some adjustments. Be aware that the NeoPixels use an 800 KHz protocol and have a PWM rate of about 400 Hz, so you might notice pixelation if the LED is moving. For smoother results, consider using DotStars. Maintenance is simple. Keep the ring clean and avoid exposing it to extreme temperatures or moisture.
