I've seen some indication that maybe 5v for power is needed; would connecting a 3.3 signal work in that case? Don't want to let out the magic smoke!</p>
<p dir="auto">From <a href="https://cdn-shop.adafruit.com/product-files/1138/SK6812+LED+datasheet+.pdf" target="_blank" rel="noopener noreferrer nofollow ugc">https://cdn-shop.adafruit.com/product-files/1138/SK6812+LED+datasheet+.pdf</a>, it looks like--with a 5V supply--Vih is 3.4V, and 3.3V isn't going to hit that. But all those are "typical".</p>

And the StampS3 running on USB 5V actually outputs out 3.3V at the RGB output...<br />
So, YES!</p>
