SparkFun Electronics will be closed in observance of memorial day on Monday, May 29th. We will resume normal business hours on Tuesday, May 30th. Any orders placed after 2pm Mountain Time on Friday, May 26th will process and ship out on Tuesday, May 30th.
Description: This is the NeoPixel Stick from Adafruit, a small chainable board with eight 5050 WS2812 RGB LEDs. The WS2812s are each addressable as the driver chip is located inside the LED. Each NeoPixel Stick has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and requires 5V.
Every stick is equipped with a single data line with a very timing-specific protocol requiring a real-time microconroller with a 8MHz or faster processor such as an AVR, Arduino, PIC, mbed, etc. There are solder pads on the back for connecting wires or breadboard pins and two mounting holes for securing this board to many different surfaces.

The solder pads are not that well bonded to the pcb, use as low a heat as possible, when soldering, otherwise, an excellent product!
I use it to get the Naza Fligthcontroller Status LED signal on different places on the Multicopter so i can allways se the status of my fligtcontroller,
The NeoPixel stick was very useful teaching my college class on Microprocessors. It was a very visual way to shift/set/clear bits especially for those very new to the ‘guts’ of a microcomputer. Plus, they’re just fun.
I really like working with these “smart” RGB LEDs (Adafruit NeoPixels and DotStars) because they make it easy to create a colorful lightshow using very little hardware apart from the microcontroller (I’m using the Arduino Pro Mini 328 and the Adafruit Trinket) and the RGB LED module(s).
The only observation I can make about the NeoPixel Stick is a self-inflicted issue: I managed to cause some of the solder pads on three different sticks to lift-off the PCB rendering it difficult/impossible to daisy-chain another stick because of the absence of the Dout line.
Edit — I hadn’t read the post by the other customer who noted the issue with the solder pads before I posted my review.
