Furthermore, based on serial received data, the controller controls the brightness and colors of the RGB LED. The serial controller has a SISO (serial in serial out ) 24-bit register which takes data serially, stores data in the register.

It consists of RGB LED dies, a serial programmable controller, and a 5050 LED package. The following figure shows the internal components of WS2812B RBG LED. The link to the datasheet is provided at the bottom of the article. The power supply is common between the control unit and RGB Led.įor more information about the technical details, switching and electric characteristics, check the WS2812B datasheet.To avoid any distortions of signals, a built-in reshaping circuit is provided.It has a power and electric reset circuit within its package.Reverse biased voltage protection that is the driver IC is not damaged even if the power supply is connected in reverse.Some of the cool features of WS2812B are :

Input signal voltage : -0.5 to VDD+0.5Volts.Power supply voltage(VDD) : +3.5 to +5.3Volts.WS2812B RBG LED Features and Specifications The pin configuration details are listed below in the tabular form: Number
