WS2812B 40 RGB LED WS2812 5X8 Pixel Dot Matrix Shield Addressable LED Module Board for Arduino UN0 R3

Description WS2813B is an intelligent externally controlled LED light source that integrates a control circuit and a light emitting circuit Its appearance is the same as a 5050 LED lamp bead each element is a pixel The pixel contains the intelligent digital interface data lat ch signal shaping amplifier driving circuit and also contains a high precision internal oscillator and a 12V high voltage programmeble constant current control part which effectively guarantees that the color of the pixel light is highly consistent The data protocol adopts the single line zero return code communication method After the pixel is reset after power on the DIN end accepts the data transmitted from the controller The 24 bit data sent first is extracted by the first pixel and sent to the pixel In the data latch the remaining data is shaped and amplified by the internal shaping processing circuit and then forwarded to the next cascaded pixel through the DO port Each time a pixel is transmitted the signal is reduced by 24 bits The pixels adopt the automatic reshaping and forwarding technology so that the n umber of cascades of the pixels is not limited by the signal trans mission only the signal transmission speed requirements LED has the advantages of low voltage drive environmental protection and energy saving high brightness large scattering angle good consistency ultra low power and ultra long life By integrating the control circuit on the LED the circuit becomes simpler
