WS2812 16 bits (square):
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 provide a complete external control pixel. Built-in signal shaping circuit, each one pixel after receiving the signal through the waveform shaping and then output to ensure line waveform distortion will not accumulate. Integrated power-on reset and brown-out reset circuit. Raster color 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 additional circuits. When the refresh rate of 30 frames / sec, cascading number of not less than 1024 points. Data transfer speeds of up to 800Kbps. The color of the light is very consistent, cost-effective.
