The RGB LED module KY-009 is made of a SMD full-color LED. The intensity of the three primary colors (red/blue/green) can be adjusted through the PWM voltage input of the three pins R, G, and B to achieve a full-color color mixing effect. The control of the module can achieve cool lighting effects.

1. Use 5050 full-color LED
2. RGB three primary colors are connected to current-limiting resistors to prevent burnout
3. The three primary colors can be mixed to obtain different colors by adjusting the PWM
4. It can be interfaced with various single-chip microcomputers
5. Working voltage: 5V
6. LED drive mode: common cathode drive
