KY-009 3-Color Full Color RGB LED SMD Module
Surface-Mount RGB Lighting for Arduino, ESP32, and Microcontroller Projects
The KY-009 3-Color Full Color LED SMD Module is a versatile, compact light-emitting board designed to add vibrant, multi-color illumination to custom microcontroller projects. Featuring an integrated 5050 surface-mount (SMD) RGB LED, this module combines red, green, and blue light chips into a single low-profile package. By applying Pulse Width Modulation (PWM) signals to the individual control pins, you can mix varying intensity levels of all three primary colors to generate a full spectrum of colors, including white, custom hues, and dynamic lighting transitions.
Engineered for seamless prototyping, the KY-009 breakout board provides clearly labeled pinouts for Red (R), Green (G), Blue (B), and a common ground pin (GND). Its small surface-mount footprint makes it a space-saving alternative to traditional 5mm DIP LEDs, fitting easily into compact project enclosures and breadboard setups. Fully compatible with 3.3V and 5V logic levels from Arduino, ESP32, Raspberry Pi, and STM32 platforms, this module is an ideal choice for status indicators, ambient lighting setups, interactive displays, and beginner electronics tutorials.
