Features:

• RGB LED module consists of a plug-in full color LED made by R, G, B three pin PWM voltage 
input can be adjusted section three primary colors (red/blue/green) strength in order to achieve full color mixing effect. Control of the module with the Arduino can be achieved cool lighting effects.
• the use of plug-in full-color LED
• RGB trichromatic limiting resistor to prevent burnout through the PWM adjusting three primary colors can be mixed to obtain different colors with a variety of single-chip interface 
• the working voltage: 5V
• LED drive mode: common cathode driver
