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.

Differences:

IC Type

SK9822 light strip uses SK9822 built-in IC, and SK6812 light strip also support built-in IC.

Color

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.

PIN Configuration

PIN Configuration

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.

Strip Voltage

SK9822 light strip can only support 5V voltage, while SK6812 can support 5~24V.

Voltage Drop

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.

If you are concerned about voltage drop, you can learn about Suntech Lite’s latest voltage-drop-free LED strip.

Refresh Rate

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.

Similarities:

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.

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.

Conclusion
