Dynamic RGBW LED Strip SK6812 IC.There are 60 addressable RGBW LEDs per meter, DC 12V power supply, strip can be cut every 3 leds (5cm). It is the digitally addressable type of LED strip. You can schedule thisdynamic led strip with 8-bit PWM precision (so 24-bit per pixel color). The LEDs are controlled by shift-registers which are chained along the strip so that you can shorten or lengthen the strip. Only 1 digital output pin is needed to send data.

PWM is built into every LED chip. SK6812 is very similar to WS2812B and can be used as a drop-in replacement in most applications because it has the same interface and color order (so LED strips based on SK6812 and WS2812B can be chained together). The main difference between the two drivers is that the SK6812 has voltage independent color and brightness over a wide voltage range, meaning that the colors of the LEDs should not be affected by a drop in supply voltage as much as they are on the WS2812B.
