Be the star at any event with our NeoPixel Jewels! These jewels feature seven tiny 5050 (5mm x 5mm) smart RGB or RGBW LEDs mounted on a beautiful round PCB. With mounting holes and a chainable design, they're our most elegant NeoPixel board yet, perfect for evening wear. Control multiple jewels with just one microcontroller pin. Each LED is addressable as the driver chip is inside. They have ~18mA constant current drive, ensuring consistent color even with voltage variations, and no external choke resistors are needed for a slim design. Power them with 5VDC and you're good to go. The jewels are chainable by connecting the output of one to the input of another. A real - time microcontroller like AVR, Arduino, PIC, mbed is required as the protocol is timing - sensitive. It won't work with Linux - based microcomputers or interpreted microcontrollers. Our well - written Neopixel library for Arduino supports these pixels. An 8MHz or faster processor is needed. Each jewel comes as a single round board with 7 individually addressable LEDs, already assembled and tested. Our detailed NeoPixel Uberguide has all the info you need for NeoPixels in any form, including ready - to - go library and example code for various Arduino models. It may ship with either WS2812B or SK6812 - based LEDs, which have the same brightness, color, and protocol.
Using the NeoPixel Jewels is easy. First, power the jewels with 5VDC. Then, connect them together by linking the output of one jewel to the input of another if you want to use multiple jewels. You'll need a real - time microcontroller like an Arduino to control them. Remember, you can only use one microcontroller pin to control all the chained jewels. When it comes to programming, our Neopixel library for Arduino can help you out, but make sure your processor is 8MHz or faster. As for maintenance, keep the jewels in a dry and cool place. Avoid exposing them to extreme temperatures or humidity. If you're having trouble, refer to our detailed NeoPixel Uberguide which has all the example code and instructions for different Arduino models. Also, note that it may come with either WS2812B or SK6812 - based LEDs, but they work the same way.
