NeoPixel Jewel - 7 x 5050 RGBW LED w/ Integrated Drivers - Warm White - ~3000K

PRODUCT ID 2858

Be the belle of the ball with the NeoPixel Jewel! These NeoPixel Jewels now have 4 LEDs in them red, green, blue, and white for excellent lighting effects. This is the Warm White RGBW version. We also have this jewel in Natural 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 fit seven of our tiny 5050 5mm x 5mm smart RGBW LEDs onto a beautiful, round PCB with mounting holes and a chainable design to create what we think is our most elegant and eveningwear appropriate NeoPixel board yet. 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 Jewel 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 microconroller 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 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.

Comes as a single round board with 7 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
