Description
WS2813B is an intelligent external control LED light source that integrates control circuit and light-emitting circuit . Its appearance is the same as a 5050 LED lamp bead, each element is a pixel. The pixel contains a smart digital interface data latch signal shaping amplifier driving circuit, and also contains a high-precision internal oscillator and a 12V high-voltage programmable constant current control section, which effectively ensures that the color of the pixel light is highly consistent .
The data protocol uses a single-line zero-code communication method. After the pixels are reset after power-on, the DIN end accepts the data transmitted from the controller. The 2 4bit data sent first is extracted by the first pixel and sent to the pixel The internal data latch, the remaining data is reshaped and amplified by the internal shaping processing circuit, and then forwarded to the next cascaded pixel point through the DO port. After each pixel point is transmitted, the signal is reduced by 2 4bit . The pixel adopts the automatic shaping and forwarding technology, so that the number of cascades of the pixel is not limited by the signal transmission, only the signal transmission speed requirement is limited.
LED has the advantages of low voltage driving, environmental protection and energy saving, high brightness, large scattering angle, good consistency, ultra low power, and long life. Integrating the control circuit on the LED makes the circuit simpler, smaller, and easier to install.
Voltage: 4.5 ~ 5.2V
Color: red
● Intelligent reverse connection protection, the reverse power supply will not damage the IC.
● The IC control circuit and LED point light source share one power supply.
● The control circuit and the RGB chip are integrated in a 5050 packaged component to form a complete external control pixel.
● Built-in signal shaping circuit, after any pixel receives the signal, it will be outputted after waveform shaping to ensure that the line waveform distortion will not accumulate.
● Built-in power-on reset and power-down reset circuits.
● The three primary colors of each pixel can achieve 256 levels of brightness display, complete the true color display of 16,777,216 colors , and the scanning frequency is not less than 400Hz / s .
● Serial cascade interface, can receive and decode data through one signal line.
● When any two-point transmission distance does not exceed 5 meters, no additional circuit is required.
● When the refresh rate is 30 frames / second, the number of cascades is not less than 1024 points.
● Data transmission speed can reach 800 Kbps .
● Light color is highly consistent and cost-effective.
Main application areas
● LED full-color luminous character string, LED full-color module, LED full-color soft light bar, hard light bar, LED guardrail tube.
● LED point light source, LED pixel screen, LED special screen, various electronic products, electrical equipment marquee.

Exchange or return policy
Every item comes with a 30-day warranty. However, there are certain conditions that apply:
-
The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).
-
The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).
-
The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.
Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:
- Provide a detailed description of the damaged item(s).
- Mention any tests or experiments conducted by the customer.
Please note that the store reserves the right to make the final decision regarding product replacement or refund.
