SK6812 (WS2812B) is a digital addressable LED strip. This strip is internally equipped with a controller chip (embedded). This makes it possible to control each LED individually in color and brightness. SK6812 is available in a full digitally controllable full-color pixel with both RGB and RGBW LED chips. Can transmit data at a speed of 800 kbps. This chip runs PWM at approximately 1.1 kHz. The SK6812 also has a built-in reset circuit and power failure reset circuit. Tests show that SK6812 works better than WS2812B and has a very low failure rate.
