WS2812B 5050 RGB LED Carrier PCB

This generated KiCad project adapts the existing 24 mm round LED carrier style to a single WS2812B 5050 addressable RGB LED.

• Board outline: 24 mm circular carrier.
• Mounting: four M2 NPTH holes on a 12 x 12 mm pattern.
• LED: WS2812B 5050 PLCC-4, centered on the board.
• Headers: two 1x02 2.54 mm side connectors. Left side is DOUT/5V; right side is GND/DIN.
• DIN is routed directly to the LED for a cleaner single-LED carrier. Add an external 220-470 ohm series resistor only when the controller lead is long or noisy.
• Top copper is intentionally simple: one visible route for each LED foot (VDD, DOUT, GND, DIN).
• Local supply stability: 0.1 uF 0603 capacitor on B.Cu; it connects from the back side through the side header pads so it does not appear as another LED leg on the top render.

Datasheet Notes

The WS2812B datasheet identifies the package as a 5050 integrated RGB LED and controller. The pinout used here is:

1. VDD
2. DOUT
3. VSS
4. DIN

Run it from a nominal 5 V supply. If the controller is 3.3 V logic while the LED is powered at 5 V, use a level shifter or verify that the DIN high level still meets the datasheet threshold.
