Recently I bought new pixels and they do not work with my Feather board running the Adafruit_NeoPixel library.

Everything magically started working!\r\n\r\nIt seems the new WS2811 is not compatible with the 3.3V logic the Feather emits.\r\n\r\nI did not need to upgrade the library from 1.0.6 to 1.1.1 for things to start working. But I did test with version 1.0.6 and 1.1.2 and everything works with either version of the library as long as I use a lower voltage like you suggested.\r\n\r\nThanks again.\r\n\r\nI'll purchase a logic level shifter and try the sacrificial pixel technique too."}}
