Each pixel of the three primary color can archive 256 brightness display, completed 16,777,216 color display. Power the whole thing with 5VDC ( 3.5V ~ 5.5V works) The pixels are arranged in a ZigZag layout, i.e. pixel(row,column): DI-(1,1)-(1,2)-(1,3)-(2,1)-(2,2)-(2,3)-(3,1)-(3,2)-(3,3)-DO. The LEDs are chainable by connecting the output of one matrix into the input of another. These pixels have full 24-bit color ability by the built-in controller chip. Since the LED is so bright and compact, you need less current/power/space to get the effects you want.
