WS2812B RGB LED Module 4pin

The WS2812B RGB LED Module is a small board carrying a WS2812B addressable RGB LED with a 4-pin connection. The WS2812B has its own driver chip, so one data wire from an Arduino, ESP32 or Raspberry Pi Pico sets its colour and brightness, and several modules can be chained so each LED is controlled on its own.

WS2812B RGB LED Module Specifications

• LED: WS2812B RGB LED with integrated driver
• Colour control: 8 bits per red, green and blue channel (24-bit colour)
• Supply voltage: 5 V
• Control: single-wire serial data, about 800 kbps
• Chaining: data out of one LED feeds data in of the next
• Connections: 4 pins (check the board markings for power, ground and data)

WS2812B RGB LED Module Applications

• Status and notification lights
• Colour indicators on robots and enclosures
• Custom lamps and ambient lighting
• Learning addressable LEDs with the Adafruit NeoPixel or FastLED libraries

What's in the Box

• 1 × WS2812B RGB LED module

Tip: Share ground between the module and your controller, and add a 300–500 Ω resistor in series with the data line. On 3.3 V boards such as the ESP32, a logic level shifter on the data line makes it more reliable.
