White/Black WS2812 Pixel LED Ring

Newstar's ws2812 Pixel LED rings are chainable - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each WS2812 LEDs is addressable as the driver chip is inside the LEDs. Each one has 18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC.

  • White/Black WS2812 Pixel LED Ring Spec,

    Chip: WS2812B
    LED: 5050 package, RGB full color, high light
    Voltage: 5V
    Interface: VCC,GND,DIN,DOUT
    Ports: Digital
    Platform: Arduino microcontroller
    LED Qty: 1/8/12/16/24/32/40/48/60/93/241LEDs

    There is a single data line with a very timing-specific protocol.
    Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, A rduino, PIC, mbed, etc.
    It cannot be used with a Linux-based microcomputer or interpreted microcontroller, such as the netduino or Basic Stamp.

    Intelligent reverse polarity protection, power supply reverse polarity will not damage the IC.
    IC control circuit and a power LED spot light utility.
    Control circuit chip with RGB components in a package in 5050, to form a complete external control pixels.
    built-in signal shaping circuit, any one pixel after receiving the signal through the waveform shaping and then output to ensure line waveform distortion will not accumulate.
    Built-in power-on reset and brown-out reset circuit.
    trichromatic color of each pixel can realize 256 highlighted, complete 16777216 colors of all true color display, the scanning frequency is not less than 400Hz / s.
    serial cascade interface, through a signal line to complete the receiving and decoding of data.
    transfer transmission distance between any two points in less than 5 meters without any additional circuitry.
    When the refresh rate of 30 frames / sec, cascading number of not less than 1024 points.
    data transmission speeds of up to 800Kbps.
    The color of the light highly consistent, cost-effective.
