## Description

20 AWG 3-wire extension cable with JST SM connector, used to extend the connection between a WS2812 or WS2811 addressable LED strip and the controller or power supply. The red, green, and white wires are easy to identify for power, data signal, and ground; the conductor is copper with PVC insulation, and the 300 VDC rated voltage covers any 5 V or 12 V installation. Suitable for LED installations, control panels, and DIY projects with addressable strips.
The JST SM 3-pin extension cable is used to extend the connection between an addressable LED strip and the controller or power source that drives it, keeping the power wire, data wire, and ground separate. It is suitable for setups where the controller or power supply cannot be placed next to the strip, for runs through walls or furniture, and for DIY decorative or special-effect lighting projects.
The cable has 3 x 20 AWG wires, each a different color, for quick identification of each wire’s role during connection. The conductor is copper with PVC insulation, and the insulation’s rated voltage is 300 VDC, which easily covers common 5 V or 12 V installations for addressable LED strips. The maximum operating temperature is 80 °C.
Among the main features are the 3 colored wires in red, green, and white, the copper conductor with PVC insulation, and the JST SM 3-pin connector type; the cable itself is not powered, but serves only to extend the power and signal path between the power source or controller and the LED strip.
The cable is compatible with WS2812 and WS2811 addressable LED strips, as well as other 12 V RGB strips, and can be used between them and any dedicated LED strip controller or development board such as Arduino or ESP32 that drives addressable strips, as long as the wire order is respected at both ends.

Usage:
Identify the 3 wires by color, red, green, and white, typically used for power, data signal, and ground.
Connect the end toward the controller or power supply so that the red wire goes to the positive power output, the green wire to the data output, and the white wire to ground.
Connect the end toward the LED strip so that the red wire goes to the strip’s power pin, the green wire to the DIN data pin, and the white wire to the strip’s ground.
Respect the data signal direction; the green wire must always go to the input end of the strip, usually marked DIN or with arrows indicating the signal direction, never to the DOUT end.
Do not reverse power and ground, to avoid damaging the LED strip or controller.
Solder or crimp the joints at both ends and insulate each joint with heat-shrink tubing to prevent short circuits and wire oxidation over time.
For long strips or high-current loads, power the strip additionally from the far end as well, to reduce voltage drop along the cable length.
Do not exceed the cable’s 300 VDC insulation rating or its 80 °C maximum operating temperature.
