In short, WS2811 chip is a high performance, low power consumption, digital programmable LED driver chip, widely used in LED light belt, LED screen, LED decoration and other fields.
The WS2811 pin is the name of a digital LED driver chip, which is a highly integrated device that includes a digital modem, LED driver, and clock module.
The main function of the chip is to provide digital control for the LED, and support the control of the protocol, adjust the CMOS level output and other functions.
In the LED strip products that use this chip, it is usually necessary to use the pin of this chip with the pin of the LED lamp bead to achieve the effect of controlling the LED lamp.
The main parameters of the chip include the number of input digital lights, color depth, maximum brightness, working voltage and so on.
At the same time, it is also necessary to use the chip through the corresponding control software to achieve the control and adjustment of the LED light.
The WS2811 pin is an LED light with a built-in IC chip, and its function is to control the color and brightness of the LED light through the data signal.
Among them, the data signal needs to be transmitted through a single bus, and the I\/O pin of the IC chip of each lamp can be connected to the data pin of the next LED lamp, so as to realize the series control of multiple lights. Parameters of
WS2811 include operating voltage range, operating temperature range, control mode, etc., which need to be selected according to specific use scenarios and requirements.
WS2811 pin is widely used in LED lights, LED screens and other LED lighting equipment, it can achieve a variety of dazzling lighting effects through simple program control.
At the same time, the advantages of WS2811 also include high reliability, bright colors and other characteristics, so by the majority of science and technology enthusiasts and engineers love and application.
The WS2811 pin function is to control the brightness and color of the digital LED lamp, including the input voltage of 5V, the maximum current of 18mA, and the transmission rate of 800Kbps.
WS2811 as a commonly used digital LED light driver chip, can be controlled through serial communication, easy to use, stable effect.
In the specific application, it is also necessary to adjust the brightness, color and other parameters according to the specific scene to achieve the best effect.
The WS2811 pin has three functions: data cable, power cable and ground cable. Among them, the data cable is used to communicate with the MCU to control the color, brightness and other properties of the LED lamp, the power cord provides the electrical energy required for the operation of the LED lamp, and the ground wire and the power cord provide grounding for the LED lamp.
Its parameters include maximum current and maximum voltage.
The maximum current is generally 20 mA, while the maximum voltage is 5 volts. In addition, the WS2811 pin is often used in LED digital light strips, LED dot matrix screens and other devices, through the above parameters and communication methods and other characteristics, to achieve a wide range of applications in the field of LED control.
The WS2811 pin has three functions of data input, power supply and ground, and its parameters are as follows: the input voltage is 5V DC, the data rate is 800Kbps, and each pixel requires 3 bytes of data.
WS2811 pin is widely used in digital light strips, and it is widely used in applications such as TV background light, interior light, and building exterior lighting.
