5mm Diffused RGB LED 4‑Pin Common Cathode 🔴🟢🔵

This RGB LED combines Red, Green, and Blue emitters in a single 5mm diffused package with a wide 60° viewing angle. It features a common cathode (negative) configuration: the longest lead is the cathode (-), while the three remaining leads are individual anodes for R, G, and B. Drive each color with a suitable current‑limiting resistor to mix colors via PWM from an Arduino, Raspberry Pi, or any microcontroller module.

Key Features ✨

• 5mm diffused lens for soft, uniform color mixing
• Common cathode design simplifies control of individual color channels
• 60° viewing angle for excellent visibility in indicators and displays
• Ideal for Arduino, Raspberry Pi, and other electronics components projects
• Great for PWM color mixing, status indicators, and DIY electronics modules
