Introduction to SK6812 chip
Introduction to SK6812 chip
Product overview:
Sk6812 is an intelligent external controlled LED light source integrating control circuit and light emitting circuit. Its appearance is the same as a 5050LED lamp bead, and each component is a pixel point. The interior of the pixel contains an intelligent digital interface data latch signal shaping and amplifying drive circuit, and also contains a high-precision internal oscillator and 12V high-voltage programmable fixed current control part, which effectively guarantees
The color of the pixel point light is highly consistent.
The data protocol adopts the communication mode of single-line return to zero code. After the pixel is powered on and reset, the DIN end accepts the data transmitted from the controller. The 24bt data sent first is extracted by the fourth pixel point and sent to the data latch inside the pixel point. The remaining data is amplified by the internal shaping circuit and then forwarded to the next cascaded pixel through the DO port. After each transmission of a pixel, the signal is reduced by 24bit. The pixel adopts automatic shaping and forwarding technology, so that the number of cascaded pixels is not limited by signal transmission, but only limited signal transmission speed.
LED has the advantages of low voltage drive, environmental protection and energy saving, high brightness, large scattering Angle, good consistency, ultra-low power, ultra-long life and so on. The control circuit is integrated on the LED, and the circuit becomes simpler, smaller and easier to install.
