WS2812B addressable RGB LEDs use a single-wire NZR protocol on a 3-pin connector (power data ground) allowing thousands of individually controllable LEDs to be chained on one data pin from a microcontroller.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | VCC | 5V power supply | PWR |
| 2 | DATA | Single wire NZR data signal | BUS |
| 3 | GND | Ground | GND |
