Product description: WS2812: Built-IC-WS2812 is the main part of the driver IC integrated into the 5050RGB normally use SMD LED beads inside. His advantage is that the circuits are integrated into the lamp beads inside and outside the circuit can be omitted, thus reducing the circuit design, reducing external components, reducing the volume, reducing the failure rate, reduce the cost of production. . . ● Control circuit chip with RGB components in one package in 5050, 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 the line waveform distortion will not accumulate. ● Built-in power-on reset and power-down reset circuit. ● trichromatic color of each pixel of the display brightness can achieve 256, 16777216 colors to complete a full true color display, scanning frequency of not less than 400Hz / s. ● serial cascade interface, via a signal line to complete the reception and decoding of data. ● pass transmission distance between any two points in less than 5 meters without any additional circuitry. ● When the refresh rate of 30 frames / sec, the low-speed mode number is not less than 512 points cascade, high-speed mode is not less than 1024 points. ● data transmission speeds of up to 800Kbps. ● highly consistent color of light, cost-effective. WS2812 is a set of control circuit and lighting circuit in one of the intelligent external control LED light source. Its appearance and an identical 5050LED lamp beads, each component is the one pixel. Pixels contained within the intelligent digital interface data latch signal shaping amplifier drive circuit also includes a high-precision internal oscillator and 12V high-voltage programmable constant current control section, effectively ensuring the color pixel light highly consistent. NRZ data protocol uses a single line of communication, the pixels on the POR, DIN terminal to accept the data transmitted from the controller, the first sent over 24bit data is extracted after the first pixel, to the internal pixel data latches, the remaining data processing circuit through the internal plastic shaping amplified through the DO output port begins forwarding to the next cascade of pixels, each pixel through the transmission of a signal to reduce 24bit. Pixel automatic forwarding shaping technology, making the number of cascaded pixel unrestricted signal transmission, only limited by the signal transmission speed requirements. LED has a low voltage drive, high energy saving and environmental protection, brightness, scattering angle, consistency, and ultra-low-power, long life and other advantages. The LED control circuit is integrated in the above, the circuit becomes more simple, small, and easy installation.
