Description:The RGB LED module is made of a patch of full-color LED,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 color mixing effect. For Arduino is used to control module can realize cool light effect.Product characteristics: 1, use 5050 full-color LED 2, the three primary colors RGB connection with the current limiting resistance to prevent burn 3, can be mixed in different colors by adjusting three color PWM 4, with a variety of single-chip interface 5,working voltage: 5V 6,LED driver mode:common cathode
