KY-011 2 Colour LED Module

3mm Two color LED module KY-011 for Arduino, emits red and green light. You can adjust the amount of each color using PWM.

This module consist of a common cathode 3mm red/green LED and a 0Ohm resistor, Since operating voltage is 2.0v ~2.5v you'll need to use limiting resistors to prevent burnout when connecting to the Arduino.
