questions about Fairy Lights - Addressable RGB https://www.sparkfun.com/products/16792

Concerning this product: Fairy Lights - Addressable RGB https://www.sparkfun.com/products/16792

The page says the part is addressable

The ‘features’ tab says “Control IC: SPI” the ‘documents’ tab has a datasheet the same.

The hookup guide link jumps into the middle of a tutorial on “ws2812” and their wiring.

I know that the “ws2812” protocol is not SPI.

Can someone explain how this product is controlled.

Thanks in advance.

That looks like a typo in the data sheet that our web folks copied over too the product page. I’ll get that fixed on the product page but there isn’t much I can do for the manufacturers data sheet. :frowning:

Thanks but I’m not sure that answer the underlying question. Do these use the same protocol as ws2812, e.g. neopixels?

Yes, they use the WS2812 protocol, same as Neopixel. :slight_smile:

That you for your quick responses. Based on your FAQ I was actually expecting a much slower turn-around.

There is something I meant to mention previously and it slipped my mind. If you go to the product page https://www.sparkfun.com/products/16792

The page shows an image and 5 thumbnails. The 3rd thumbnail (red patch) has poor solder joints, with solder balls near one of the wires.

For me, this gives more info on the layout of the strand; but OTOH it reflects poorly on SF.

Sorry about that!

This isn’t a product SparkFun makes, we just resell it so sadly there isn’t anything we can do about the solder balls.

Looks like the manufacturer (iPixel) probably is using a wee too much solder paste on their boards during manufacture and that can cause solder balls to form.

FYI…

The Fairy Lights - Addressable RGB (5m) PRT-16792 in the 09-Mar-2021 batch are wired opposite of what is specified on the packaging or in the Sparkfun WS2812 Breakout Hookup Guide.

Socket (male housing) is input… Blue = 5V, Middle = DAT, End = GND.

thank you
