Each LED contains a control circuit and RGB chip, enabling individually addressable color control via a single-wire data protocol.+An addressable RGB LED with the controller built into the 5050 package, the WS2812B is the chip behind NeoPixel strips. Red, green, and blue dies plus a control IC sit under one lens, driven by a single data line: the host sends 24 bits of color (8 each for G, R, B) to the first LED on DIN, and each LED latches its own color then forwards the rest of the stream out DOUT to the next one. So a whole strip of hundreds runs from one microcontroller pin. It runs on 5 V and needs only a decoupling capacitor. Four pins: VDD, DOUT, VSS, DIN.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VDD | power_in | Power supply for the internal controller and the RGB LED. Absolute range +3.5 to +5.3 V; recommended operating VDD 4.5 to 5.5 V. Decouple with a 100 nF (104) ceramic capacitor per pixel per the reference schematic. |+| 2 | DOUT | output | Cascaded serial data output. After latching the first 24-bit color word, the pixel reshapes and re-drives the remaining bit stream out of DOUT to the DIN of the next WS2812B. Transmission delay tPLZ <= 300 ns with CL=15 pF, RL=10 kohm. |+| 3 | VSS | power_in | Ground reference (0 V) for the controller and the RGB LED drivers. |+| 4 | DIN | input | Serial control-data input using a single-wire NZR protocol at 800 Kbps (bit period TH+TL = 1.25 us +/- 600 ns). VIH >= 0.7*VDD, VIL <= 0.3*VDD, hysteresis ~0.35 V. A low period >= 50 us is interpreted as the RES/latch (reset) code. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Addressable RGB LED (integrated IC) |+| Color depth | 24-bit (8 bit per channel) |+| Interface | single-wire (DIN to DOUT chain) |+| Chainable | yes (data reshaped at each LED) |+| Data rate | 800 kbps |+| Refresh | ~400 Hz (30-LED cascade) |+| Supply voltage | ~3.5-5.3 V |+| Package | SMD-5050 (4-pin PLCC) |++## Ordering variants++- `WS2812B (5050)`+- `WS2812B-B (reverse-mount 5050)`++## CAD (KiCad official)++- Symbol: `LED:WS2812B`+- Footprint: `LED_SMD:LED_WS2812B_PLCC4_5.0x5.0mm_P3.2mm`+- 3D model: WS2812B 5050 (KiCad packages3D)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Worldsemi datasheet](https://cdn-shop.adafruit.com/datasheets/WS2812B.pdf) (5 pp, sha256 `670517e400d01f76`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
