The KY-029 Dual Color LED Module is a minimalist, beginner-friendly breakout board featuring a single 5mm LED capable of emitting both red and green light independently or simultaneously to produce a yellow/orange blend. Designed for seamless compatibility with Arduino, ESP32, ESP8266, Raspberry Pi, and similar microcontroller platforms, this module is perfect for building simple two-state indicators, status lights, and visual alert systems without the complexity of a full RGB setup.
With its 3-pin interface — red, green, and ground — the KY-029 connects directly to any digital or PWM-capable output pin, requiring no resistors or additional components. Its compact PCB and standard pin spacing make it fully breadboard-compatible and easy to integrate into both prototyping and finished project enclosures.
Whether you’re signaling pass/fail conditions, building a traffic light simulation, or adding dual-color feedback to a sensor project, the KY-029 offers a clean, reliable, and cost-effective solution for hobbyists and electronics enthusiasts at every skill level.
