Description WS2813 (WS2812B) Introduction WS2813 is an upgraded version of the first generation of built-in driver IC-WS2812, in 2011 began research and development, in October 2012 officially put into the market. After the placement test during the IC crystal, crystal line link test, and fluorescent plastic anti giant cold test. . . It took almost a year. WS2812 IC products built at the beginning of the market, customers have been a little contradiction, because he is a new product is not easy to be accepted, but also because he really broke the conventional drive IC plus lamp beads concept. But look at today, almost all lighting manufacturers, application providers, decorative advertising works so accepted the built-in IC products, but also are keen on the production and use of the built-in IC products. The reason I believe we all know, because he really is more stable than the traditional, more concise, more beautiful, more performance, production and more convenient. WS2813 IC is built the second generation, even better than the first generation WS2812. It contains all the advantages of the first generation WS2812 WS2812 also better than all of the advantages. WS2813 is 4 pin 5050RGB lamp bead type. Pin fewer, more stable; lamp beads bracket brighter, better, higher brightness; circuit more compact, higher performance, production costs are lower; new positive and negative level reversal protection, not pick the wrong line It will burn. Features: The control circuit chip and RGB components in a package in 5050, to form a complete external control pixels. Built-in signal shaping circuit, any one pixel signal is received 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 of the display brightness can achieve 256, 16777216 colors to complete the full true color display, the scanning frequency of not less than 400Hz / s. Serial cascade interface, through a signal line to complete the receiving and decoding of data. Biography transmission distance between any two points in less than 5 meters without any additional circuitry. When the refresh rate of 30 frames / sec, the number of low-speed mode cascade of not less than 512 points, the high-speed mode is not less than 1024 points. Data transmission speeds of up to 800Kbps. Light color highly consistent, cost-effective. Application: LED full-color light-emitting character string lights, LED full-color module, LED full-color flexible light strip light bar, LED guardrail. LED spot light, LED pixel screen, LED shaped screen, a variety of electronic products, electrical equipment marquees. Documentation on this page.
