NeoPixel Stick - 8 x 5050 RGBW LEDs - Natural White - ~4500K

PRODUCT ID 2868

What is better than smart RGB LEDs? Smart RGB+White LEDs! These NeoPixel sticks now have 4 LEDs in them red, green, blue and white for excellent lighting effects. These are fun and glowy, and you can control each LED individually! Make your own little LED arrangement with this stick of NeoPixel LEDs. This is the Natural White RGBW version. We also have this stick in Warm White, Cool White, and good ole RGB! The NeoPixel is 'split', one half is the RGB you know and love, the other half is a white LED with a yellow phosphor. Unlit, it resembles an egg yolk. Lit up these are insanely bright like ow my eye hurts and can be controlled with 8-bit PWM per channel 8 x 4 channels = 32-bit color overall . Great for adding lots of colorful + white dots to your project! We crammed 8 of the tiny 5050 5mm x 5mm smart RGBW LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC 4-7V works and you're ready to rock.

NeoPixel LEDs use 800 KHz protocol so specific timing is required. On NeoPixels, the PWM rate is ~400 Hz, which works well but is noticable if the LED is moving. In comparison, DotStars have a 20 KHz PWM rate, so even when moving the LED around, you won't see the pixelation, the blending is very smooth. we recommend DotStars if you can use them

The LEDs are 'chainable' by connecting the output of one stick into the input of another. There is a single data line with a very protocol. Since the protocol is very sensitive to timing, it requires a microcontroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Our written Neopixel library for Arduino supports these pixels! As it requires assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required. We have a tutorial showing wiring, power usage calculations, example code for usage, etc. for NeoPixel Please check it out! Please note you will need a NeoPixel library with RGBW support which is not always available. If you try to control these with a plain 'RGB' NeoPixel library, you'll get very weird results. Our Adafruit NeoPixel library does support RGBW but if you're using something else, just be aware that it might require some hacking.

Comes as a single stick with 8 individually addressable RGBW LEDs assembled and tested.

Our detailed NeoPixel Uberguide has everything you need to use NeoPixels in any shape and size. Including library & example code for the Arduino UNO/Duemilanove/Diecimila, Flora/Micro/Leonardo, Trinket/Gemma, Arduino Due & Arduino Mega/ADK all versions
