75mm Bars - 12V Digital RGB LED Pixels Strand of 21 - WS2801

PRODUCT ID 1548

RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each plastic PVC 'pixel bar' contains 3 RGB LEDs and a controller chip soldered to a PCB. The pixel is then 'flooded' with epoxy to make it waterproof. These are fairly large pixels but they have a lot of nice mounting options, such as two plastic flanges on the ends with 0.15"/4mm diameter holes and also some sticky foam tape on the back for easy attachment. They're typically used to make outdoor signs. Compared to our other LED dots, these are much bigger and much brighter, good for larger scale installations. They'd also make great large RGB 7-segment displays which is why we have them in strands of 21 not

The pixels are connected by a 4-conductor cable. +12VDC, ground, data and clock. 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.

Sold by the strand, each strand has 21 pixels in series! Each strand has two JST SM 3-pin connectors so you can connect multiple strands in a row, as many as you wish, just watch for how much current they want. The two power wires are brought out separately to make wiring easier, a 2.1mm terminal block adapter is handy here to attach a DC power supply. We have a 12V/5A supply that should be able to drive 3 or more strands depending on current use . The LEDs are constant-current
driven so you'll have even colors through-out the strand as long as you have a stable 12V supply

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!. Since these are nearly identical in how they work to t he 36mm pixels, that guide will get you blinking
