ALLNET 4duino Two Colour LED Module (Red/Green) - 5mm Bi-Color Digital LED for Arduino, Raspberry Pi

The ALLNET 4duino Two Colour LED Module is a compact and versatile digital LED module designed for makers, educators, and hobbyists. Featuring a 5mm bi-color LED with red and green emission, this module is ideal for visual indicators, status displays, and educational projects. It operates at 3.3V-5V DC and uses a standard 3-pin digital interface (GND, Red_Pin, Green_Pin) with common cathode configuration. Integrated current-limiting resistors simplify wiring and ensure safe operation. Compatible with Arduino, Raspberry Pi, and other microcontrollers, this module is a reliable choice for adding dual-color output to your projects.

Advantages

Easy to integrate with any 3.3V or 5V microcontroller thanks to onboard resistors and standard 2.54mm pin header. Dual-color capability (red/green) allows for clear status indication. Compact PCB design with through-hole LED ensures durability and easy mounting.

Suitable for

• Arduino and Raspberry Pi projects
• Status indicators and visual alerts
• Educational electronics kits
• Prototyping and DIY electronics
