NeoPixel Ring - 16 x 5050 WWA LED with Integrated Drivers
What is better than smart LEDs? Smart WWA LEDs! These NeoPixel rings now have 3 white LEDs in them in three tints (also known as 'color temperatures'): warm white, cool white and amber, great for excellent lighting effects that want pure white lite. These are fun and glowy, and you can control each LED individually! Make your own little LED arrangement with this stick of NeoPixel LEDs.
Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75" (44.5mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. 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 and you're ready to rock.
This is the WWA version. We also have this ring in Warm White RGBW, Natural White RGBW, Cool White RGBW, and good ole RGB!
The NeoPixel is mainly white LED with a yellow phosphor. Unlit, each section 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 bright white or warm tone dots to your project!
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 microconroller 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. Our wonderfully-written Neopixel library for Arduino supports these pixels! 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.
Comes as a single ring with 16 individually addressable WWA LEDs assembled and tested
