1.RGB LED module is made of full-color LED with patch. Through the R, G, B three pin PWM voltage input can be adjusted three primary colors ( red / blue / green ) strength in order to achieve full-color mixing effect. Control of the module with cool lighting effects can be achieved. 2.Using 5050 full color LED. 3.RGB trichromatic limiting resistor to prevent burnout. 4.Through the PWM adjusting three primary colors can be mixed to obtain different colors. 5.With a variety of single-chip interface. 6.Operating voltage: 5V. 7.LED drive mode: common cathode driver.
