Can Pixhawk4 control neopixel?

Holybro pixhawk 4 control neopixel?

I change to
・servo5_function = 120

But LED can’t flash

Did you give it the correct voltage? Can you describe your setup a bit more?

Yes. using 5.1V output.
Please check attached photo.

Better use an external 5V supply. Don’t supply from possibly tiny internal components inside the Pixhawk.


You might have an issue with the signal level.
Look at the wiki for options:
