This RGB LED rings can work with AVR, forArduino, RPI, PIC, mbed etc.
Voltage: DC4-7V, usually we use USB 5V to power it, current draw at 5 V is around 1.44amps(60 mA per LED,24 X 0.6 = 1.44 amps.)
LED Chip: WS2812B; Communication interface: Single-wire communication.You can set the led brightness in the arduino-code, and also you can program each light individually
Note: the 60 bits ring is 4 pieces of separate 1/4 ring , you need solder them together by yourself, package without any cables
What you will get is: 1 X 60Bits WS2812B 5050 RGB LED Rings
