RGB 5050 SMD LED Module — Full Color, PWM, Common Cathode, 3.3–5V (2-Pack)

This RGB LED module integrates a single 5050 SMD full-color LED with onboard current-limiting resistors for each channel (R, G, B), making it safe to drive directly from 3.3V or 5V microcontroller GPIO pins without external resistors. The common cathode configuration and PWM-compatible inputs allow smooth color mixing across 16 million colors when driven by Arduino, ESP8266, or Raspberry Pi. Supplied as a 2-pack.

Key Specifications

Arduino Wiring Guide

R → Arduino PWM pin (e.g. D9)
G → Arduino PWM pin (e.g. D10)
B → Arduino PWM pin (e.g. D11)
GND → GND
Use analogWrite(pin, 0–255) to mix colors

Why Choose This RGB LED Module?

✅ Onboard current resistors — no external resistors needed, direct GPIO connection
✅ 3.3V / 5V compatible — works with Arduino, ESP8266, ESP32, Raspberry Pi
✅ PWM color mixing — 16 million colors via analogWrite
✅ Common cathode — standard configuration, compatible with most LED libraries
✅ 2-pack value — one for prototyping, one for the final build
