SK6812 as new type of 5050 RGB LED Pixel,it is similar to our APA104 LED WS2812B , they are 4pin, RGB dimming,can use the same PCB of ws2812b and apa104.
It is stable as apa104,ws2812b. Also SK6812 can be compatible with ws2812b apa104 controllers . SK6812 full color RGB led strip provide us one more choice.
SK6812 IC Overview
SK6812 is a set of smart control circuit and a light emitting circuit in one of the controlled LED source. The outer type is the same with a 5050LED chip, each element is a pixel. Pixels contained within the intelligent digital interface data latch signal shaping amplification circuit,power supply circuit, a built-in constant current circuit, high precision RC oscillator, the output is driven by the patented PWM technology,effectively guarantee the pixels in the color of the light high consistency. Data protocol using unipolar NRZ communication mode, the pixel is reset after the end of DIN, accept the data transmitted from the controller to the 24bit, the first to send data by the first pixel to pixel extraction, internal data latch, the remaining data after the internal plastic the processing circuit after shaping amplification through the DO port output began to turn to the next cascade of pixels, each pixel through a transmission signal, reduce. Pixel using automatic shaping forwarding technology, makes the number of cascade without signal
transmission limit of the pixel, only limited signal transmission speed.The LED has a low driving voltage, environmental protection and energy saving, high brightness, scattering angle, good consistency, low power,long life and so on. The control circuit is integrated in the LED above,more simple circuit, small volume, easy installation.
