Overview

The KY-016 RGB LED Module is a versatile, 3-color light-emitting diode breakout board designed for microcontrollers such as Arduino, Raspberry Pi, and ESP32. It features a 5mm common-cathode RGB LED capable of generating a full spectrum of colors (red, green, blue, and custom color mixes like yellow, cyan, purple, and white) using Pulse Width Modulation (PWM). The module includes onboard current-limiting resistors (labeled ‘121’ = 120 Ω) on the red, green, and blue channels to protect the LED chips and ensure stable operation across standard microcontrollers.
