(3 pin female 0.100" keyed with latch) seems to be similar to the retired 4-pin part# PRT-11182. The LED strip I just received has this connector which is not a JST PRT-09915 mate. How about a vendor and series name to find this connector elsewhere? Thanks<p>FOUND THEM at ebay from yongqinghuang

I looked for it but perhaps I just missed it the first time. I will see if it does the trick, tonight.<p>Thanks.</p></p>

Am I missing something? I have not found any actual guidance on programming/connecting these using an Uno.<p>I am not sure if it applies but I found what appears to be a similar product over at pololu site with tutorial on uploading a sketch, etc. I haven't tried it yet, I would rather get the info here, if possible.</p><p>Can anyone offer guidance on powering and programming these using an UNO?</p></p>

You'll have to figure out how to power the LEDs however (you won't be able to power several meters of LEDs through the ribbon alone).</p>

Can I just turn some leds on and play with their colors?
I only need to control 12 leds rgb (bottom, middle, and at the end of the strip).
Thanks</p>

No idea if you can plug them into the EH or XH board connectors reliably. Push comes to shove, I'd just crimp a new connector onto the cable, or replace the cable altogether.</p>

But it would be easy enough to cut out each pixel and add in wire between them to give you the flex you need</p>

From <a href="https://www.sparkfun.com/products/11821#comment-52080285ce395f4735b3471b" rel="nofollow">another user's comment</a>:<blockquote>
<p>the WS2812B. It looks like the WS2812 but it has 4 pins instead of 6. The low-pass filter seems to be built-in now so it does not have seperate power pins for the LEDs and the logic</p>

The reason i ask is the 1m units are out of stock but i see ws2182b 1m units on other sites. Trying to figure out if they are same product. time is critical, otherwise i would wait for them to be back in stock.</p>

The note in the product description indicates there's a separate 2 wire power connector in addition to the 3 wire data/control connector. However, the 2 wire power connector is not clear from the photos or individual LED silkscreens, and the example circuit in the WS2812 datasheet shows VCC and VDD sharing a +5V power rail through a 150 ohm resistor to VCC. If the individual LEDs can be "cut free", then only the 3 wire connector would seem plausible according to the photos...</p>

Some forms seem to indicate that the raspberry pi can not hand the timing requirements of the WS2812 and recommend using the ws2801 instead.</p>

Looks like they do, but the data sheet isn't super clear about that. I can see that the bit order is a bit odd, but I can deal with that.
