On the HUZZAH32, in Arduino code, is pin A2 referred as “A2” or “2” or “34” (for GPI 34)?
I find each used in example code and I’m not sure.
Thank you.

Hi David.
I don’t have an Adafruit Huzzah32 to experiment. But I would recommend using just the GPIO number “34”. Referring the pins that way prevents errors assigning the pins, and it should be compatible with all ESP32 models.
