WS2812 Neopixel Ring with 8 RGB LEDs and Rings can be Cascaded as only 1 MCU I/O Pin is used for control and 32mm Outer Diameter with 4~7V power supply
WS2812 Neopixel Ring with 8 RGB LEDs
Round and black shape, this is great for making interesting project.
8 ultra bright smart LED NeoPixels are arranged in a circle with 32mm outer diameter.
The rings are cascaded connected – connect the output pin of one to the input pin of another. Use only one MCU I/O pin to control as many as you can chain together!
Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external resistors are required making the design slim.
Power Supply : 4-7V DC
WS2812 use a single data line DO communication protocol, but a very timing-specified.
This ring board can be driven by AVR 8mhz MCU, such like AVR, PIC, Arduino, etc.
WS2812 required a capacitor, but it is already designed on the board.
