Product Description: RGB LED Ring WS2812B 5050 x 24 LEDs - 90 mm
Ring composed of 24 individually addressable RGB LEDs with integrated driver. One pin of the microcontroller, e.g. Arduino, is enough to operate the module. The diodes are placed in equal distances on a circle with the outer diameter of 86 mm. Each of them consumes up to 18 mA, which in this case gives a total value of about 440 mA. The ring can be supplied with 5 V.
The communication protocol used allows the diodes to be connected in series. The next chain should be connected to the output connector, connecting respectively 5V, GND and DOUT from DIN. The manufacturer notes that when using more than 500 diodes, there may not be enough RAM in the Arduino Uno chip.
Product is compatible with Arduino and Raspberry Pi.
The product works with NeoPixel libraries from Adafruit:
- Arduinolibrary on GitHub along with connection examples,
- connection example with Raspberry Pi along with code.
