I’ll be hiding the PB inside a semi-translucent structure with the LEDs. Is there a way to turn off the blue light on the PB, so that it doesn’t shine through as well? Besides putting a little electrical tape over the blue LED, of course.
Unfortunately it’s hard wired on the module. If you don’t need ws281x support you can cut the jumper on the bottom and that should help.
Otherwise a blob of paint, tape, or desoldering it will do the trick.
