RGB 3 colors LEDs module (SMD) เป็น Module LED แบบ 3 สี สามารถผสมสีกันได้โดยใช้สัญญาณ PWM 

Features :

The use of plug-in full-color LED

RGB trichromatic limiting resistor to prevent burn out

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

Description :

"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.

LED drive mode: common cathode driver
