Step into the spotlight with the NeoPixel Jewel! These jewels come with 4 LEDs (red, green, blue, and white) for amazing lighting effects. This is the warm white RGBW version, and we also offer natural white, cool white, and classic RGB options. The NeoPixel is unique, with one half being the familiar RGB and the other a white LED with yellow phosphor. When lit, it's incredibly bright. You can control it with 8-bit PWM per channel, giving you 32-bit 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. You only need one microcontroller pin to control as many as you can chain. Each LED is addressable as the driver chip is inside. It has a ~18mA constant current drive, ensuring consistent color even with voltage variations, and no external choke resistors are needed. Power it with 5VDC (4 - 7V works). NeoPixel LEDs use an 800 KHz protocol, so specific timing is required. The PWM rate is ~400 Hz, which works well but may be noticeable if the LED is moving. DotStars have a 20 KHz PWM rate and smoother blending. We recommend DotStars if possible. The LEDs are chainable by connecting one Jewel's output to another's input. It requires a real-time microcontroller like an AVR, Arduino, PIC, or mbed. It can't be used with Linux-based or interpreted microcontrollers. Our well-written Neopixel library for Arduino supports these pixels. An 8MHz or faster processor is needed. It comes as a single round board with 7 individually addressable RGBW LEDs, assembled and tested. Our detailed NeoPixel Uberguide has all you need to use NeoPixels of any shape and size, 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 also works). Connect one Jewel's output to another's input if you want to chain multiple jewels together. You'll need a real - time microcontroller like an AVR, Arduino, PIC, or mbed to control it. Make sure your processor is 8MHz or faster. Our Neopixel library for Arduino can help you get started quickly. When using it, be aware that the NeoPixel LEDs use an 800 KHz protocol, so timing is important. The PWM rate is about 400 Hz, and if you move the LED, you might notice some pixelation. For smoother results, consider using DotStars. To maintain the NeoPixel Jewel, keep it in a dry and clean environment. Avoid exposing it to extreme temperatures or humidity. If you're not using it for a long time, store it properly. And don't forget to check out our detailed NeoPixel Uberguide for more tips and ready - to - go code for different Arduino models.
