Choosing between LED pixel lights can be as challenging as picking a movie for family night. You’ve got to consider everyone’s preferences, right? In the world of LED lighting, it’s all about your project’s requirements. Today, we’re comparing two popular models: the WS2814 and the SK6812. Which one will light up your project? Let’s find out.
WS2814 vs SK6812, What's the difference?
Here we made a comparison table to show the differences and similarities between WS2814 vs SK6812.
Table: WS2814 vs SK6812 LED Strip
|Item||WS2814 LED Strip||SK6812 LED Strip|
|IC Type||WS2814 external IC||SK6812 built-in IC|
|PIN Configuration||12 pins||4 pins|
|Data Wire||Dual-wire data transmission||Single-wire data transmission|
|Signal Transmission Distance||5M||10M|
|Individual Control||DC5V: Yes;|
|Price||Higher (++)||Lower (+)|
|Data Transmission Speed||800Kbps||800Kbps|
|LED Strip Color||RGBW||RGBW|
From the above table, we can learn that the refresh rate of WS2814 and SK6812 IC is the same 2KHz, and the data transmission speed is 800Kbps. They are both 256 grayscale, and both are in addressable RGBW color. Next, let’s compare WS2814 and SK6812 LED strips across several key factors to help you understand and differences.
The WS2814 pixel LED strips use external ICs to drive the groups of LEDs, and SK6812 LED strips use integrated built-in ICs to drive each LED individually.
- External IC vs Built-in IC
External IC: Integrated circuit mounted on PCB as an independent chip, connected via pins.
1. Flexible: Easy replacement and upgrade for maintenance and expansion.
2. Independent debugging: Can be debugged without impacting the entire circuit board.
Signal Interference: Susceptible to external interference due to longer pin connections.
Built-in IC: Integrated circuit embedded inside the LED, connected to the circuit board.
High reliability: Strong connection with the circuit board, resistant to external factors.
1. Difficult to repair: Replacement of the entire board may be necessary in case of failure.
2. Design restrictions: Design considerations during PCB manufacturing limit modification and upgrade flexibility.
PIN configuration refers to the arrangement or layout of pins on an electronic component, such as an integrated circuit (IC), connector, or other devices with physical pins.
The WS2814 IC is a 12 pins external IC, and the 12 pins are: data out (DOUT), output white color (OUT W), output blue color (OUT B), output green color (OUT G), output red color (OUT R), voltage direct drain (VDD), data input (DIN), ground (GND), 3pcs no connection (NC), and backup input (BIN).
The SK6812 IC is a 4 pins built-in IC, and the 4 pins are: voltage direct drain (VDD), data output (DOUT), data input (DIN), voltage supply source (VSS).
The main difference is that the WS2814 IC has separate output pins for each color channel, SK6812 IC combines the R, G, B, W color on a single pin. Moreover, the external 12-pin WS2814 IC is more stable than the built-in 4-pin SK6812 IC due to it has a backup data channel.
The WS2814 addressable LED strips support 5V~24V, but SK6812 can only be DC5V. The wide voltage range makes the WS2814 LED strip suitable for more lighting and decoration scenarios. The DC5V limits the SK6812 pixel LED strip is more suitable for small LED lighting projects.
Data Wire and Break Continue
The WS2814 RGBW LED strips have two data wires, one is used for normal data transmission and the other is for backup. The backup data wire gives the break continue (breakpoint resume) function to WS2814 strip light.
The SK6812 strip lights only have one single data wire and don’t have the break continue function.
- What is Break Continue?
The break-continue means if one pixel on the strip is broken, the backup wire can still transmit the data to the next LED through the breakpoint. The video below takes WS2815 and SK6812 light strips as examples to show what the breakpoint resume is.
Signal Transmission Distance
The signal transmission distance means the maximum distance that can be connected between two pixels without affecting the signal stability.
The maximum pixel spacing distance of WS2814 pixel strip is 5m, and SK6812 supports 10m cable connection without signal weakness.
To avoid signal weakening in any connection situation, you can use the signal amplifier. Please check the following video to see what is signal amplifier and how it works:
Voltage drop is related to the voltage, the higher the voltage, the lower the voltage drop. The 5V WS2814 and SK6812 LED strips have the most serious voltage drop problem, and need to power again every 5 meters. For the 12V WS2814 light strip, limited by the voltage drop, it needs to be powered every 10m. For 24V strip light, it needs to be powered every 15m.

All the SK6812 RGBW LED strips and DC5V WS2814 LED strips support individual control due to the built-in IC design. DC12V and 24V light strips cannot be controlled one by one LED.
Price and Availability
Typically, LED strips with dual data wires, such as the DC24V WS2814 RGBW 60leds LED strip, tend to be more expensive compared to LED strips with single data wires, such as the DC5V SK6812 RGBW 60leds LED strip.
The SK6812 is generally more affordable and widely available than the WS2814, making it a popular choice for a range of projects.
