What is the difference between a 3-pin and 4-pin JST connector cable?

This 3-pin cable is for single-signal addressable LED strips (Power, Data, Ground). A 4-pin cable is typically used for standard RGB strips (R, G, B, Power) or dual-signal addressable strips.

Is this extension cable compatible with WS2812B LED strips?

Yes, it is fully compatible. WS2812B strips use a 3-wire connection (5V, Data In, GND) and typically come with 3-pin JST SM connectors.

Can I connect multiple extension cables together for a longer run?

Yes, you can chain them. However, for total extension lengths over 5-10 meters, you should be mindful of potential voltage drop, which can impact the performance of your LED strip.

Do I need to do any soldering?

No, this is a completely solderless solution. It features pre-attached male and female JST SM connectors for a simple plug-and-play installation.

What does JST SM stand for?

JST is a Japanese manufacturing company (Japan Solderless Terminal), and SM is a specific series of wire-to-wire connectors they produce, known for its reliable locking mechanism.

What wire gauge are these cables?

These cables use 22AWG tinned copper wire, which is a standard and suitable gauge for most addressable LED strip applications over these lengths.

Application Scenarios

Large-Scale Architectural Lighting Effortlessly bridge gaps between long runs of addressable LED strips on building facades, in coves, or across large spaces without signal loss. This cable ensures your dynamic lighting effects remain perfectly synchronized.

Custom DIY Projects & Signage Ideal for creating custom lighting fixtures, illuminated art, or complex digital signage. Use these extensions to navigate corners, connect separate segments, and cleanly route wiring for a professional finish.

Convenient Controller Placement Place your Addressable Dream Color Controllers in a hidden or easily accessible location away from the strip itself. This cable provides the extra length needed to connect your controller to the start of your lighting installation cleanly.

How to Use This Extension Cable

Ensure all power is disconnected from your LED strip and controller before making any connections.
Identify the male and female ends of the extension cable and your LED strip's connectors.
Connect the female end of the extension cable to the male connector of your LED strip or controller.
Connect the male end of the extension cable to the female connector of the corresponding LED strip segment.
Verify the pinout alignment. The arrows on the connectors should align, ensuring V+, Data, and GND are correctly matched.
Once all connections are secure, restore power and test your lighting setup.

⚠ Precautions

While you can chain multiple extensions, be mindful of potential voltage drop over very long total distances, which may affect brightness and color accuracy at the far end of the strip.
