7)Connectors: 4PIN JST female and male connectors, DAT, CLK, DC5V+, GND-.these LEDs have 2 wires (input and out put) for sending data - one clock pin and one data pin.That means you need two pins, not one, to control DotStars. Because the clock and data is seperated, you can use any processor   speed or type to control these strips, and you don't have to worry about being careful with the timing. 

8)LED Brightness: Red ~600mcd, Green ~500mcd, Blue ~150mcd
