CJMCU-WS2813B is a set of control circuit and light-emitting circuit in one of the intelligent external control LED light source. Its appearance and a 5050LED lamp beads the same, each component is a pixel. The pixel contains the intelligent digital interface data latch signal shaping amplification drive circuit, also includes a high-precision internal oscillator and 12V high-voltage programmable constant current control part, effectively ensure that the pixel light color is highly consistent .
Data protocol using single-line zero code communication, pixel point after power-on reset, DIN side to accept the data transmitted from the controller , the first sent over 2 4bit data is extracted after the first pixel, sent to the pixel The internal data latch, the remaining data through the internal shaping circuit after shaping the amplification through the DO port began to forward the output to the next cascade of pixels, each after a pixel transmission , the signal reduced by 2 4bit . The pixel adopts the automatic shaping forwarding technology, so that the number of cascades of the pixels is not limited by the signal transmission, only the limited signal transmission speed requirements.
LED with low voltage drive, environmental protection and energy saving, high brightness, scattering angle, consistency, and low power, long life and other advantages. The control circuit integrated in the LED above, the circuit becomes more simple, small size, the installation is more simple
