Compact 5 V WS2812B Light Ring

This 30 mm by 57 mm RGB ring uses the WS2812B driver chip and runs on a single 5 V supply. It communicates through a one-wire interface so a microcontroller can address each LED individually. The small circular board suits tight spaces in robotics or wearable projects. Builders needing a larger diameter or a different voltage should look elsewhere.

Single-wire control simplifies coding

Only one data line is required to drive the full-colour LEDs, reducing pin count on the host board. The ring arrives as a single unit with no extra cables or mounting hardware included. Users must provide their own 5 V power source and write the control firmware. Projects that demand plug-and-play lighting strips or pre-soldered connectors are not a match for this component.

Questions about this item

How often will the WS2812B LEDs need replacement under continuous 5 V operation?

The WS2812B LEDs are rated for tens of thousands of hours at 5 V; no scheduled replacement is required unless a diode fails.

What thermal limit appears first when the 30 mm × 57 mm ring runs at full white brightness?

The 5 V supply current becomes the limiting factor before the PCB reaches its maximum temperature rating.
