The pinout and datasheet information for that board does not appear to be publicly available. Do you have its pinout information?

Which pin on the AMB82-MINI is the NeoPixel's DIN connected to? Are you changing the code in the strandtest.ino to match the pin being used? Without the actual pinout information...

> I just assign one GPIO pin to drive WS2812B LED's DIN Which pin? What does this line of code look like in your sketch? ```cpp #define LED_PIN 6 ```

This library is known to work fine on ESP32, ESP8266, and others. If it is not working for your specific setup, then more information is needed. At this point, it...

That nominally seems OK in terms of pin set in code. It could be other things like power and logic level. Try that other library and report back here if...

So the issue is not specific to this library. You are also seeing issues using the amebaiot examples and library. Please open this issue in their forums: https://forum.amebaiot.com/

> The neopixel failed to work, and on the S2 and S3 it guru-meditated. Found out they set these values as the pin number plus the count of pins... That...

That's a really weird pin numbering scheme. Not sure it's worth adding logic in this library to automagically deal with that. Best that translation be done in user code. Can...
