Note: these strips are sold by the meter! it will be a cut piece from a reel which may or may not have a connector (2 or 3-pin jst) on it and have separated power/ground wires. To wire up these strips we suggest picking up some jst sm plug and receptacle cables. you'll want one of each, one wire is for ground the other is for signal. for the power wire, you will also probably want a 2.1mm dc jack to wire in so you can connect one of our wall adapters to power it these led strips are even more fun and glow. there are 60 rgb leds per meter, and you can control each led individually! yes, that's right, this is the digitally-addressable type of led strip. you can set the color of each led's red, green and blue component with 8-bit pwm precision (so 24-bit color per pixel). the leds are controlled by shift-registers that are chained up down the strip so you can shorten or lengthen the strip. only 1 digital output pin are required to send data down. the pwm is built into each led-chip so once you set the color you can stop talking to the strip and it will continue to pwm all the leds for you. The strip is made of flexible pcb material, and comes with a weatherproof sheathing. you can cut this stuff pretty easily with wire cutters, there are cut-lines every 0.65"/1.7cm (1 led each). solder to the 0.1" copper pads and you're good to go. of course, you can also connect strips together to make them longer, just watch how much current you need! we have a 5v/2a supply that can drive to 1 meter (depending on use) and we have a 5v/10a supply that can drive up to 4 meters(depending on use) you must use a 5v dc power supply to power these strips, do not use higher than 6v or you can destroy the entire strip.
