neopixels on the nRF52840

Thanks for the image. So the above with Arduino uses a longer array to write out the eight colors. was that suggestion tried? (ref larger array)

And we confirm on board regulator is sufficent to drive 8 Neopixels using Arduino code block? (Yes?)

'I don't think it's the circuit nor the neopixels itself.'

Would have to agree (for #6 image - is that an Arduino and not the DK board?):

EDIT: But the link in #8 post is to a different board that what is shown in #6 image

EDIT:
Are we able to rule out the delay fetching the module across the web?

I may have to eat crow on that one. I just took a look at some working code from two years ago, and I used the require within a function call. I've also re-read my notes and just realized the Neopixel module is now a part of the current release, so it isn't (now) fetched across the web as it was when I developed then.

That strip seems to the the WB2812B and pretty common and easy to work with.


FWIW: I had a heck of time many months ago, until I could confirm squaring up of the data line with a level shifter, and the correct leading start pulse length. I don't know the nRF52840DK and that may not even be a consideration as it is confirmed with the Arduino #6 post image.
