Hi,

I've spent hours trying trying to make this work, but no such luck. Do I have a defective board?
Arduino: 1.8.15 (Windows 10), Board: "SparkFun ESP32 Thing, 80MHz, Default, 921600, None"

                            ^

Error compiling for board SparkFun ESP32 Thing.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Ended up uninstalling Arduino IDE, purging all related files, reinstalling, and the errors went away. Not only that, the thing compiled! :)
