Key Features
- This is the 8 LED RGBW NeoPixel stick in Cool White.
- Uses 800 KHz protocol so specific timing is required
- NeoPixels are 5050-sized LEDs
- 8 ultra bright smart LED NeoPixels
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.
Adafruit 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.
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!
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 timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microcontroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. As it requires hand-tuned 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.
Item Specific
1 - Stick with 8 RGB LEDs
Dimensions: 10.2mm x 51.1mm x 3.2mm / 0.4" x 2.0" x 0.13"
Weight: 2.6g
May ship with either WS2812B or SK6812-based LEDs. They are the same brightness, color and protocol.
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
