About this item

• Mini Traffic Light LED Display Module, 5V Red Yellow Green Signal Light Board with Digital Control Interface, 3.3V–5V Compatible for arduino for Raspberry Pi DIY ProjectsThis LED display module features three vertically arranged LEDs in red, yellow, and green to simulate a traffic signal layout. Each LED is controlled independently through digital input signals, enabling flexible light sequence programming in electronic projects.
• Operates on a 5V DC supply and is compatible with both 3.3V and 5V logic control signals. This allows direct connection to common microcontroller platforms without additional level conversion components.
• Uses a common cathode design with separate control pins for each color. The structure simplifies wiring and allows individual control of red, yellow, and green LEDs through GPIO or PWM signals.
• Compact module size with three 5mm LEDs mounted on a small PCB. The vertical LED arrangement provides clear visual separation of each color, making it suitable for demonstration models and timing‑based control experiments.
• Suitable for educational electronics projects, signal control simulations, and embedded development tasks. The module can be integrated into breadboard setups or mounted in custom enclosures for prototype systems.
