From the table above we can see that there are many differences and similarities between SK9822 and SK6812 addressable LED light strips. Now, let’s compare SK9822 and SK6812 based on several important factors.
SK9822 supports RGB effects, while SK6812 can support RGB and RGBW. Therefore, the SK6812 LED light strip has stronger color mixing capabilities and better color expression.
SK9822 strip lights use 6 PIN configuration IC, and SK6812 uses 4 PIN configuration IC.
For 6-pin configurations, common pin functions include power (VCC) pin, clock line input (CKI) pin, clock line output (CKO) pin, data output (SDO), data input (SDI) pin, and Ground (GND) pin. This configuration facilitates signal transmission and has a break-point continue function.
The 4-pin SK6812 is relatively simple. The pin functions include a power supply (VDD) pin, a data output (DOUT) pin, a data input (DIN) pin and a ground (VSS) pin.
SK9822 light strip can only support 5V voltage, while SK6812 can support 5~24V.
The voltage drop will be higher when using a 5V light strip, and the higher the voltage, the smaller the voltage drop. Therefore, SK6812 can support smaller voltage drop than SK9822.

The maximum serial input data rate of the SK9822 is 30MHZ, while the SK6812 is only 1MHZ.
Clock Wire and Clock Date
SK9822 has a signal line and a clock line, so it has clock date while the SK6812 has a single signal line and no clock date.
SK9822 and SK6812 LED strips are all color-changing pixel LED strips, so they have some similarities.
- Data transmission speed can reach 800Kbps.
- 256 Gray Level: The PWM control terminal can realize 256 levels of adjustment.
- Individual control: Support individual control.
Deep Dive into SK9822 and SK6812
After comparing SK9822 vs SK6812 digital LED strips, we now dive into the specifics of each kind of LED strip.
SK9822 LED Pixel Light
What is SK9822 LED Pixel Light
SK9822 has a maximum serial input data rate of 30MHZ and is a two-wire data transmission. The double data transmission, built-in support uninterrupted oscillation PWM output, can maintain a static image. Therefore, SK9822 is more suitable for display screens than SK6812.
Features of SK9822 LED Strip
The SK9822 operates at a 5V power supply. It features an individual control and dual-data-wire design, meaning each LED can receive and transmit signals, allowing for seamless communication even if one LED fails.
SK6812 Pixel Light
What is SK6812 LED Pixel Light
The SK6812 has a wider color spectrum, including RGB, RGBW, WWA and white light. And SK6812 can support external IC. Therefore, SK6812 can support smaller voltage drop and can be suitable for working under voltages of 5V, 12V and 24V.
Features of SK6812 LED Strip
The most significant advantage of the SK6812 LED light strip over the SK9822 is that it can produce more colors than the SK9822, providing superior color mixing capabilities and enhanced flexibility for custom color schemes. SK6812 can support RGBW, while SK9822 can only provide RGB.
Choosing between SK9822 vs SK6812
When choosing between SK9822 vs SK6812 LED strips, it’s essential to consider their specific features and your project requirements. When choosing between these three options, consider the following factors:
- Power supply compatibility: If you prefer using a 12V or 24V power supply, consider SK6812 for reduced voltage drop over longer distances.
- Project complexity: If you require more clear dynamic effects, SK9822 provide more robust fault tolerance.
Ultimately, the choice depends on your specific project requirements, such as fault tolerance, control capabilities, and power supply compatibility. Review the specifications and features of each LED strip type, and select the one that best aligns with your needs.
In conclusion, through SK9822 and SK6812, we know that the SK9822 and SK6812 strips each offer unique features, making them suitable for different applications. While they share some similarities, their differences in voltage requirements, color, and voltage drop make them better suited to different needs.
