5mm Dual LED Green–Red, Common Cathode 🔴🟢

Elevate your builds with a compact, reliable indicator LED engineered for both professionals and makers. This 5mm bi-color LED combines green and red emissions in a single package with a common cathode, making it ideal for status indication, UI feedback, and signal monitoring in Arduino, Raspberry Pi, and other microcontroller-based projects. The diffuse lens ensures a uniform glow and clear visibility on breadboards and PCBs.

Key Features ⭐

• Dual-color emission: Outputs both green and red light for versatile, space-saving indication in a single component.
• Common cathode configuration (-): Simplifies wiring with a shared ground, ideal for MCU GPIOs, driver ICs, and low-side switching.
• 5mm diffuse lens: Provides a soft, uniform glow with a balanced 30° viewing angle for improved readability and reduced glare.
• Durable and long-life: Reliable for prototypes and production designs across a wide range of electronics applications.
• Easy integration: Breadboard- and PCB-friendly, perfect for students, hobbyists, and electronics engineers working with modules and electronics components.

Technical Specifications ⚙️

• Forward Voltage (Vf): 2.0–2.4 V (Green), 1.8–2.2 V (Red)
• Forward Current (If): 20 mA (typical)
• Lens Type: Diffuse
• Wavelength: 565 nm (Green), 625 nm (Red)
• Viewing Angle: 30°
• Pin Configuration: The longest pin is the cathode (-); the two shorter pins are anodes for the respective colors.

Typical Applications 🧰

• Status indicators: Show power, signal presence, fault/OK states, and operating modes in instruments and modules.
• DIY and maker projects: Custom LED displays, Arduino shields, Raspberry Pi HATs, and general prototyping.
• Educational kits: Teaching basic electronics, logic indication, and microcontroller interfacing.

Integration Tips 🔧

• Use a dedicated current-limiting resistor for each anode to set the desired current (If), typically around 20 mA or less per color.
• Connect the common cathode to GND; drive the anodes from GPIOs, transistor stages, or LED driver ICs as needed for your voltage and current requirements.
• To blend colors (e.g., amber/yellow), drive both anodes simultaneously with appropriate currents.

Compatibility 🔌

Ideal for use with Arduino, Raspberry Pi, ESP32/ESP8266, STM32, and other microcontroller platforms. Seamlessly fits into breadboard prototypes and custom PCBs across a wide range of electronics components and modules.
