LED Matrix RGB 4x4 16Bit WS2812 Module Board

The 4 x 4 WS2812 Addressable RGB LED Matrix is a compact and powerful lighting module featuring 16 individually addressable RGB LEDs. Each pixel integrates a WS2812 control circuit and RGB LED inside a single 5050 package, allowing full digital control using only one data line. This design enables smooth color transitions, accurate brightness control, and reliable cascading for larger LED arrays.

Pinout

WS2812 16-Bit RGB LED Matrix – QuartzComponents

Pin Description
VCC Power Supply 5V
GND Ground
DIN Data Input
DOUT Data Output for Cascading

Arduino Wiring

  • VCC → 5V on Arduino
  • GND → GND on Arduino
  • DIN → Digital Pin 6 (example)
  • DOUT → Connect to DIN of next module if cascading

Arduino Example Code

Uses the Adafruit NeoPixel Library.

#include "Adafruit_NeoPixel.h"

#define LED_PIN   6
#define NUM_LEDS  16

Adafruit_NeoPixel matrix(NUM_LEDS, LED_PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  matrix.begin();
  matrix.show();
}

void loop() {
  for(int i = 0; i < NUM_LEDS; i++) {
    matrix.setPixelColor(i, matrix.Color(0, 0, 255)); // Blue
  }
  matrix.show();
  delay(500);

  for(int i = 0; i < NUM_LEDS; i++) {
    matrix.setPixelColor(i, matrix.Color(255, 0, 0)); // Red
  }
  matrix.show();
  delay(500);
}
