The KS031 LED Lollipop is a 16-LED WS2812B (XL-5050RGBC-WS2812B) addressable RGB LED board in a fun circular lollipop shape. It uses the same one-wire protocol as NeoPixels, so it works with FastLED, Adafruit NeoPixel, and any WS2812B-compatible library right away.

Unlike bare LED rings sold without connectors or mounting provisions, the LED Lollipop includes polarised friction-lock XH connectors for easy wiring and disconnection, plus mounting screws for secure installation in a panel or enclosure.

Multiple boards can be cascaded — 5V, ground, and data pass through to the next board’s input connector for simple daisy-chaining.

Features:

• 16× WS2812B (XL-5050RGBC) individually addressable RGB LEDs
• NeoPixel / FastLED compatible — no custom library needed
• Single 5V supply
• Polarised friction-lock XH connectors — no loose jumper wires
• 5V, GND, and data pass-through for daisy-chaining
• Includes 2 mounting screws
• 58mm × 112mm, 2-layer PCB
