Non-Addressable RGB LED Strip Hookup Guide

February 19, 2020

Add color to your projects with non-addressable LED strips! These are perfect if you want to control and power the entire strip with one color for your props, car, fish tank, room, wall, or perhaps under cabinet lighting in your home.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    As Dre wrote 9 years ago, the insert in the package is incorrect. The green and ground pins are reversed. The downloadable manufacturer's spec sheet is correct... they don't spell out ground but you can figure it out.

      I'm not sure how it happens, but sometimes there are misprints on the insert. The ground pin should be the longest leg on a common cathode LED.

    From somewhere else:
    The included sheet is incorret, and has the green and ground pins swapped.

    I used these to illuminate paper Minecraft avatars, as indicators for when players are logged in to my server. The diffuse housing and bright LEDs illuminate the (1" cube heads of the) avatars nicely, even in bright indoor light. I can run 5 at full brightness (with the recommended 150Ω/330Ω resistors) without a problem from a USB-powered Teensy's digital out pins.

    Project notes, photos, video.

    Presumably these LEDs are the same as these:
    so they are common cathode.
    Maybe you want to add that to the info.
    (feel free to delete the comment afterwards :p)
