Each pixel can realize 256 highlighted, complete 16777216 colors of all true color display.The WS2812 are each addressable as the driver chip is located inside the LED. Each LED has about 18mA constant current drive so the color will be very consistent even if the voltage varies, and requires 5V(4-7V works).
Each board is equipped with a single data line with a very timing-specific protocol requiring a real-time microconroller with a 8MHz or faster processor such as an AVR, Arduino, PIC, mbed, etc. There are solder pads on the back for connecting wires or breadboard pins and two mounting holes for securing this board to many different surfaces.
