Single LED with WS2811 chip for self-contained.
You can control this LED with the WS2811 chip digitally. The output data is truncated and processed by the WS2811 chip , the remaining data is then forwarded to the next chip (if installed). This makes it possible to connect several hundred LEDs in series. Please consider the possibilities of your control unit. For a 24-bit color depth (for 16 million different colors), the single LED is internally controlled with an 8-bit PWM LED driver.
