RGB LED 5MM
5 mm RGB LED (4‑Pin Through‑Hole)
Overview
A classic 5 mm RGB LED, combining red, green, and blue light emitters in a single package—perfect for adding full-color effects to electronic projects. Compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers. Use PWM control to mix colors and create custom lighting effects.
Key Features
4-pin through-hole: common anode or common cathode versions
Diffused lens for smooth color blending
Individual forward voltages: approx. 2.0 V (red), 3.2 V (green/blue)
Typical max current: 20 mA/color, combined up to ~60 mA
60° viewing angle; durable plastic housing
Lifespan: 50,000+ hours
