This is a 7 LED circular module.  This module is comprised of 7 5050 LED chips.  The 5050 LED chips include 3 LED diodes per chip, red, green, and blue.  These three colors allow for the full color gamut depending on the intensity of the individual LED diodes.  They are used when you need slight illumination for your project area and especially RGB color changing lights. All 7 LEDs can be controlled with a single set of 4-pin inputs via a 5050 driver module.  All 7 LEDs are daisy-chained together.
