The KY-029 Dual Color LED module emits red and green light. You can adjust the intensity of each color using PWM.

This module consists of a  common cathode 5mm red/green  LED, a 0Ω resistor and 3 male pin headers. Use this module with limiting resistors to prevent burnout of the LED when working for long periods of time.

Compatible with many electronics platforms like Arduino, Raspberry Pi, ESP32 and others. This module is similar to the KY-011.
