Power supply: 5V Main features Intelligent reverse connection protection ensures that the IC will not be damaged when the power is reversed. The IC control circuit and the LED point light source share one power supply. The control circuit and the RGB chip are integrated in a 5050 package component, forming a complete external control pixel point. It is equipped with an internal signal shaping circuit. After any pixel receives the signal, it undergoes waveform shaping before being output, ensuring that the waveform distortion of the line does not accumulate. It is equipped with built-in power-on reset and power-off reset circuits. Each pixel's three primary colors can achieve 256-level brightness display, completing the full true color display of 16,777,216 colors, with a scanning frequency of no less than 400Hz/s. The serial cascade port can receive and decode data through a single signal line. When the transmission distance between any two points does not exceed 5 meters, no additional circuits are required. When the refresh rate is 30 frames per second, the number of cascades is no less than 1024 points. The data transmission speed can reach up to 800Kbps. The color of the light is highly consistent and the cost performance is high. Product Overview WS2813B is an intelligent external control LED light source that integrates a control circuit and a light-emitting circuit. Its appearance is the same as that of a 5050LED lamp bead, and each component is a pixel. The pixel point contains an intelligent digital interface, data latch, signal shaping and amplification drive circuit, as well as a high-precision internal oscillator and a 12V high-voltage programmable constant current control section, effectively ensuring the high consistency of the color of the pixel point light. The data protocol adopts a single-line reset code communication method. After the pixel is powered on and reset, the DIN end accepts the data transmitted from the controller. First, the 24-bit data sent over is extracted by each pixel and then sent to the data latch inside the pixel. The remaining data, after being shaped and amplified by the internal shaping processing circuit, starts to be forwarded and output to the next cascaded pixel point through the DO port. With each pixel point of transmission, the signal is reduced by 24 bits. The pixel points adopt automatic shaping and forwarding technology, which makes the number of cascaded pixel points not limited by signal transmission, but only restricted by the signal transmission speed requirement. LED features low-voltage drive, environmental friendliness and energy conservation, high brightness, large scattering Angle, good consistency, ultra-low power consumption and extremely long lifespan. Integrating the control circuit onto the LED makes the circuit simpler, smaller in size and easier to install.
