ACEBOTT China Manufacturer 4 Pin 3.3V-5V Digital Signal Output Signal Mini LED RGB Traffic Signal Light Module for Arduino ESP32
Product Description
Products Description
The traffic light module integrates three different colors of red, yellow and green LED, which has four pins, one of which is a public pin, and the other three pins respectively control three different colors of LED work. The common end GND is connected to the GND port of the controller board. Pins R, Y and G are connected to different I/O ports of the controller board respectively. When each pin R, Y and G inputs high voltage, the corresponding color LED will light up.
Application reference: Traffic lights, indicators, etc.

Frequently Asked Questions (FAQ)
What is the operating voltage of this traffic light module?
The module supports an operating voltage range of 3.3V to 5V, making it highly compatible with popular microcontrollers and development platforms such as Arduino, STM32, and Raspberry Pi.
How do I connect the module's pins to my microcontroller?
The module features 4 pins: the common GND connects to the ground port of your controller board, while pins R, Y, and G connect directly to individual digital I/O ports.
How are the individual LED lights triggered?
Each LED is controlled independently by high-level digital logic. When pin R, Y, or G receives a high voltage input, the corresponding red, yellow, or green LED lights up.
What are the physical dimensions and operating temperature limits?
The module has a compact size of 4.8 cm * 2.4 cm and is engineered for resilient performance in temperature environments ranging from -40°C to +70°C.
What applications can this module be used for?
