Description: 100PCS 3528RGB 1210 full-color LED light red, blue and green three-color SMD lamp beads There are three chips in a single lamp, which emit red light, green light and blue light respectively. One common pin connects to the other three to emit three colors (red, green, blue) Colorful and full-color can be mixed through the control of single chip microcomputer or circuit board chip. It doesn't automatically send colorful colors when you light it up! Just 3.5 mm by 2.8 mm (about the size of a match head!), the extremely low profile, "out of the way" design doesn't impede anything. The small size makes it look almost hidden.
