Step into the spotlight with the NeoPixel Jewel! These jewels now come with four LEDs - red, green, blue, and white - delivering outstanding lighting effects. This is the Natural White RGBW version, and we also offer Warm White, Cool White, and classic RGB options. The NeoPixel is unique, with one half being the beloved RGB and the other half a white LED with a yellow phosphor. When unlit, it looks like an egg yolk, but when lit, it's incredibly bright. Each channel can be controlled with 8 - bit PWM, giving a 32 - bit overall color. It's perfect for adding colorful and white dots to your projects. We've placed seven tiny 5050 (5mm x 5mm) smart RGBW LEDs on a beautiful, round PCB with mounting holes and a chainable design. It's our most elegant NeoPixel board yet. You can control multiple jewels with just one microcontroller pin. Each LED is addressable as the driver chip is inside. With a ~18mA constant current drive, the color remains consistent even with voltage changes, and no external choke resistors are needed, making the design sleek. Power it with 5VDC (4 - 7V also works). NeoPixel LEDs use an 800 KHz protocol, requiring specific timing. Their PWM rate is ~400 Hz, which works well but may show pixelation if the LED is moving. DotStars have a 20 KHz PWM rate for smoother blending (we recommend DotStars if possible). The LEDs are chainable by connecting the output of one Jewel to the input of another. The protocol is timing - sensitive and needs a real - time microcontroller like an AVR, Arduino, PIC, or mbed. It can't be used with Linux - based microcomputers or interpreted microcontrollers. Our well - written Neopixel library for Arduino supports these pixels. An 8MHz or faster processor is required. It comes as a single round board with 7 individually addressable RGBW LEDs, already assembled and tested. Our detailed NeoPixel Uberguide has all the info you need for using NeoPixels in any form, including ready - to - go library and example code for various Arduino models.
Using the NeoPixel Jewel is easy! First, power it with 5VDC (4 - 7V will also work). Connect the output of one Jewel to the input of another if you want to chain multiple jewels together. You can control them all with just one microcontroller pin. Remember, you need a real - time microcontroller like an AVR, Arduino, PIC, or mbed as the protocol is timing - sensitive. An 8MHz or faster processor is required. When programming, our Neopixel library for Arduino can be a great help. Just make sure to check if it's suitable for your Arduino model. As for pixelation, if you notice it when the LED is moving, you might want to consider using DotStars instead. For maintenance, keep it away from extreme temperatures and moisture. The LEDs have a constant current drive, so they'll keep a consistent color even if the voltage varies a bit. If you're new to using NeoPixels, our detailed NeoPixel Uberguide has plenty of ready - to - go library and example code to get you started.
