ALLNET 4duino Flash LED Module – Red, Digital I/O, 3.3-5V, Breadboard-compatible 4duino_B28

Flash LED module for visual indication and signaling in DIY electronics, compatible with Arduino, 4duino, Raspberry Pi, and other microcontrollers. Provides a simple controllable red light output via a digital HIGH/LOW signal.

Advantages

Built-in resistor allows direct connection to digital I/O pins without additional components. 3-pin header with standard 2.54mm pitch fits breadboards and prototyping boards. Operates from 3.3V to 5V DC, making it suitable for both 3.3V and 5V logic systems.

Suitable for

• Visual status indication in microcontroller projects
• Signaling and alerts in DIY electronics
• Educational experiments with Arduino and Raspberry Pi
• Prototyping and breadboard circuits
