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

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

KY-029 SPECIFICATIONS

This module consists of a common cathode 5mm red/green LED, a 0 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.

CONNECTION DIAGRAM

Well use a couple of 330 resistors to limit the current from the Arduino and prevent burning the LED.
