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

Description:
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.

Feature:
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.
