10mm PCB width 5050SMD 60LEDs/m High Density 12V/24V External SM16703 Digital RGB LED Strip. Every three lights of a segment are controlled by an external SM16703 IC chip at 12V cut each 50mm, Every six lights of a segment are controlled by an external SM16703 IC chip at 24V cut each 100mm, allowing the LEDs on different segments to be different colors. This LED strip SM16703 has a very wide application range and appropriate run length, and is the voltage of choice for most lighting projects.
This SM16703 LED has wide compatibility. Works great with Arduino, Adafruit NeoPixel Library, Fast LED library, and Raspberry Pi, etc.

SM16703 Arduino RGB LED Strip Application
• Home Theater Lighting: Accent behind the screen or color-changing ambient lighting around the room.
• Holiday Decorations: Create festive lighting displays for holidays like Christmas, Halloween, or Fourth of July.
• Wedding Lighting: Create custom lighting effects for weddings, such as a glowing backdrop or color-changing lighting accents around the venue.
• Art Installations: Can be used in a variety of art installations, such as a glowing sculpture or a light installation on a building.
How to Control SM16703 RGB LED Strip?
As a 3-pin single signal transmission addressable LED strip, SM16703 RGB LED Strip connected to the LED controller is similar to WS2811. Below is the wiring diagram of the pixel SM16703 RGB LED strip connected to the offline K-1000C LED controller.
Prepare the required equipment, mainly the SM16703 RGB LED strip, power supply, and controller. Prepared an adjustable voltage power supply, a K-1000C controller, and a roll of DC12V SM16703 RGB LED strip.
Connect the controller to the power supply. Note that the red wire is V+ and the black wire is GND.
For more wiring details, please read our blog: How to Control Connect and Wire Addressable LED Strip?
Please pay attention to the direction of data transmission before connection to avoid reverse signal connection. (If the data transmission of the SM16703 LED strip is reversed, it will cause damage to the ICs and LED beads.) The BLACK ARROWS on the LED strip tell the signal transmitting direction. If connected oppositely, the strip will not work.

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! For more SM16703 VS WS2811 LED Strip, please click to view.
Table-WS2811 LED Strip vs SM16703 LED Strip
Item | WS2811 LED strip | SM16703 LED strip |
IC | External IC | External IC |
Voltage | DC12v/24v | DC12v/DC24v |
Chip Size | 5050/2835/3535 | 5050/2835/3535 |
Color | RGB | RGB |
Break continues | No | No |
LED per meter | 30/60/120 | 30/60/120 |
Power consumption | 14w/m | 14w/m |
Wires | Positive+Negative+Single Data wire | Positive+Negative+Single Data wire |
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.
Compatibility
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.
Stability
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.
