This is the 24-LED NeoPixel Ring from Adafruit. It's a small, chainable board with an outer diameter of 2.6 inches (66mm) and is equipped with 5050 WS2812 RGB LEDs. The WS2812 LEDs are individually addressable as the driver chip is inside each LED. Each NeoPixel Stick has a ~18mA constant current drive, ensuring consistent color even when the voltage varies. It operates on 5V. Every ring comes with a single data line that follows a timing-specific protocol, requiring a real-time microcontroller with an 8MHz or faster processor like an AVR, Arduino, PIC, mbed, etc. There are solder pads on the back for wire connection or breadboard pins, and two mounting holes for securing the board to various surfaces. Documents available include the NeoPixel Überguide, NeoPixel Library, and a Product Video.
Using this NeoPixel Ring is easy. First, connect it to a real - time microcontroller with an 8MHz or faster processor like an Arduino. Make sure to use a 5V power supply. You can connect wires to the solder pads on the back or use breadboard pins. If you want to mount it, use the two mounting holes to secure it to a surface. When it comes to programming, refer to the NeoPixel Überguide and the NeoPixel Library. As for maintenance, keep it in a dry and cool place. Avoid exposing it to high humidity or extreme temperatures. If you have any issues, check the product video for troubleshooting tips.
