Description
Make your own little LED strip arrangement with this NeoPixel LED stick. We crammed 8 tiny 5050 (5mm x 5mm) smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC (4-7V works) and you're ready to rock.
The LEDs are 'chainable' by connecting one stick's output to another's input - see the photo above. There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the Netduino or Basic Stamp. Our wonderfully written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.
Comes as a single stick with 8 individually addressable RGB LEDs assembled and tested.
Our detailed NeoPixel Uberguide has everything you need to use NeoPixels in any shape and size. Including ready-to-go library & example code for the Arduino UNO/Duemilanove/Diecimila, Flora/Micro/Leonardo, Trinket/Gemma, Arduino Due & Arduino Mega/ADK (all versions)
The breadboard, cables and controller are NOT included
Note: May ship with either WS2812B or SK6812-based LEDs. They are the same brightness, colour and protocol
Revision history
- As of July 30, 2024 - This NeoPixel Stick used to come with WS2812B LEDs and now comes with SKC6812 LEDs. These are the same protocol and brightness, and are more reliable and handle accidental overvolting a little better!
