Traffic Light Module

Compact 3‑Color Traffic Light Simulation Module

This module contains an array of high‑luminosity LEDs that faithfully emulate a conventional traffic light, offering Red, Yellow, and Green outputs in a single, ready‑to‑wire package. Designed for use with Arduino, MSP430, PIC, and other microcontroller platforms, the module includes built‑in current‑limiting resistors, allowing direct connection to a 5 V IC output or a 12 V power supply through low‑current driver transistors. Its low power consumption (under 60 mA total) and robust construction make it ideal for robotics, RC car projects, and interactive learning displays.

The module’s 90‑degree angled pins and compact PCB footprint reduce assembly time while ensuring reliable solder joints on small PCB boards. With an operating temperature range of –20 °C to +60 °C and a warranty of 24 months, it delivers dependable performance in both indoor and outdoor hobby applications.

• Key Spec 1: Operating Voltage: 5–12 V (with in‑built current limiting)
• Key Spec 2: Forward Current: 20 mA per LED (total < 60 mA)
• Key Spec 3: Pin Pitch: 3.5 mm, 4‑pin header (ground, GND, Red, Yellow, Green)
• Common Use Case: Traffic light logic demonstration in robotics and RC vehicles
