Particle Argon and Neopixels


Have you tried using a multi meter to check the output voltage of the Argon 3.3V is infact 3.3V and it might be worth checking the voltage of your chosen data pin. Although its will not be 3.3V DC it should read pretty close on a DVM, check with a scope if you can.

There have be other discussions on this matter

And it looks like people cracked it. So other issues could be;

  1. Not all neo pixels are the same, some are more forgiving in pushing their limits than others. Try a different brand.

  2. Are you using a capacitor on the neo pixel DC in? You should be able to live without for just a few neopixels.

  3. Are you using a resistor on the data line. You can often live without it.
