5mm Dual-Color LED (Green/Red), Common Anode (+) 💡

Enhance your builds with this reliable 5mm dual-color (green/red) bi‑color LED in a common anode configuration. Ideal for status indication, front panels, and embedded systems, it integrates seamlessly with Arduino, Raspberry Pi, and other microcontroller-based projects. The diffuse lens delivers a soft, uniform glow with excellent visibility—perfect for prototyping, educational kits, and production electronics.

Key Features ✅

• Dual-color emission (Green/Red): Use a single package for two states or blend colors via PWM to create amber/yellow effects.
• Common anode (+): Shared positive lead simplifies wiring in circuits that source current from a common supply rail.
• 5mm diffuse lens: Wide, even illumination with a 30° viewing angle for clear status indication and reduced glare.
• Durable, long-lasting: Consistent performance for both prototypes and finished products.
• Easy integration: Through-hole T‑1 3/4 form factor fits standard breadboards and PCBs; ideal for electronics components and modules.

Technical Specifications ⚙️

• Forward Voltage (Vf): Green 2.0–2.4 V; Red 1.8–2.2 V
• Forward Current (If): 20 mA (typical per color)
• Wavelength: Green ≈ 565 nm; Red ≈ 625 nm
• Lens Type: Diffuse, 5 mm (T‑1 3/4)
• Viewing Angle: 30°
• Pin Configuration: Longest lead is the common anode (+); the two shorter outer leads are the cathodes (−) for green and red respectively
• Package: 3‑lead, through‑hole bi‑color LED

Pinout and Wiring 🔌

• Connect the common anode (+) to your positive supply (e.g., +5 V on Arduino, +3.3 V on Raspberry Pi).
• Drive each color via its cathode (−) through a series current-limiting resistor to a microcontroller GPIO or transistor.

• Recommended resistor: R ≈ (Vcc − Vf) / I. Typical values:
  

  • 5 V systems (Arduino): ~220–1 kΩ per color
  • 3.3 V systems (Raspberry Pi, ESP32): ~150–680 Ω per color

  
  

• Use PWM to adjust brightness or mix colors. For higher currents or multiplexing, drive via a transistor or MOSFET.

Applications 🚀

• Status indicators: Power, fault/OK, mode selection, TX/RX activity
• DIY and maker projects: Arduino shields, Raspberry Pi HATs, and custom electronics modules
• Education: Intro to LEDs, polarity, voltage/current limiting, and microcontroller interfacing
• Embedded systems: Front-panel indicators for instruments, chargers, and test fixtures
