The pixels are connected by a 4-conductor cable. +5V (Red), Ground

(Blue), Data (Yellow) and Clock (Green). Data is shifted down from one

pixel to the next so that you can easily cut the strand or attach more onto

the end.

Each dot is digitally controlled, with an internal 8-bit PWM LED driver (24-

bit color for 16 million different shades). The pixels must be clocked by a

microcontroller, we have an example code linked below that works on an

Arduino, it should be simple to adapt it to any other microcontroller.

The pixels use 8mm diffused RGB LEDs, with a 120 degree beam width.

The total max brightness of all LEDs is about 1600mcd but with the light

more evenly distributed & mixed than a clear LED. (Please note: mcd

ratings of LEDs are notoriously inflated by most LED sellers, so be extra-

skeptical when reviewing LED ratings!)

Sold by the strand, each strand has 25 pixels in series! Each strand has

two JST SM 4-pin connectors so you can connect multiple strands in a

row, as many as you wish, just watch for how much current they want. We

now have LED pixel strands with the power wires (red & blue) spliced out

so its really easy to connect 5VDC in using a 2.1mm jack terminal adapter.

We have a 5V/2A supply that should be able to drive 2 or more

strands and a 5V/10A supply that can drive up to 160 LEDs all lit up at

once

If you want to connect to the input of a strand (to wire it to power and a

microcontroller) please get a plug connector. If you want to connect to

the output, get a receptacle cable.

You can drive these with an Arduino using any two microcontroller digital

pins, check this library which also has example code to demonstrate the

strands and be sure to read our very detailed tutorial on usage!
