What is the difference between SM16703 and WS2811?

Both the SM16703 and WS2811 are addressable LED driver chips used in LED strips, but there are some key differences between them. Let’s look at the table first!

From the above, we can see that they have the same parameters in the perspective of the whole strip light. Now we look if they have any difference in IC.

Refresh Rate

The SM16703 has similar refresh rate as the WS2811. 

Power Consumption

The SM16703 arduino RGB LED strip is the same power consumption as the WS2811.  


The WS2811 is more commonly used and has more support in the hobbyist community. It is also easier to find libraries and code examples for the WS2811 than for the SM16703. WS2811 led strip appeared earlier and more mature than SM16703 arduino RGB LED strip.


SM16703 can be made into DC24v, while WS2811 light strip can only be made into DC12v, because the highest voltage WS2811 used Worldsemi informed is 20v, Now some manufacturers have launched the DC24v version of WS2811, but it is not stable enough. SM16703 DC24v is quite stable and has been popular in the market for a long time.

In summary, the SM16703 offers higher voltage than the WS2811, but it may be less compatible with existing code and libraries. The choice between the two chips depends on the specific needs of the project.

Frequent Asked Questions

How do I mount the SM16703 arduino RGB LED strip?

 A: The SM16703 LED strip can be mounted using a variety of methods, such as double-sided tape or mounting brackets. It is important to ensure that the mounting method used is secure and will not damage the LED strip.

Can the SM16703 LED strip be dimmed?

A: Yes, the SM16703 LED strip can be dimmed using a PWM (pulse width modulation) signal sent from a microcontroller or other type of controller. This allows for fine control over the brightness of the LED strip, and can be used to create a variety of lighting effects.

How do I program the SM16703 LED strip?

Answer: Programming the SM16703 LED strip typically involves using a microcontroller, such as an Arduino, to send control signals to the LED strip. There are many resources available online to help users get started with programming the strip, including pre-made libraries and code examples.

Can I control the SM16703 LED strip with a smartphone or tablet?

Yes, there are several apps available that allow you to control the SM16703 LED strip using a smartphone or tablet. These apps typically connect to a microcontroller, such as an Arduino, that is programmed to control the LED strip.
