I’m trying to use an Adafruit Neopixel with my new Beetle ESP32 Microcontroller however I’m getting this error message:

It looks like in the second line you are trying to import a library for the RP2040, a different chip used in the Raspberry Pi Pico. No worries though, the library will still be able to work perfectly fine.
And taking a look through your code it doesn’t look like you reference it either.
