LC8812B-3535/SK6812mini LED are pin to pin function,same lighting effect,same control way. LC8812B-3535 is an intelligent externally controlled LED that integrates a control circuit and a light-emitting circuit.Its appearance is the same as a 3535 LED . Each LED is a pixel.The data protocol adopts a unipolar return-to-zero code communication method. After the LED is powered on, the DIN terminal receives external signal data, and the data regeneration circuit automatically reshapes and forwards the cascaded output data to ensure that the data is transmitted in series without attenuation and normal transmission.
