Bit-Tree Creativity - LED Traffic Signal Light Module

LED Traffic Light Module

This LED traffic light module adopts common cathode circuitry. The red, yellow and green light channels support independent control. It accepts 3.3V–5V wide‑voltage input and equips a PH2.0 connector. Pre‑drilled mounting holes streamline installation. The unit fits programming lessons, smart scene simulation, traffic‑related DIY electronic projects.

Independent control for red, yellow and green channels

Wide input voltage range for plug‑and‑play operation

Tool‑friendly mounting built for educational use

BIT-TREE CREATIVITY

STEAM skills like programming will be a core competency for the next generation, and the time to cultivate this ability is now.
