Is there a default config for standard ESP32 boards?

[shan-mcarthur]

Many ESP32 dev boards come with a standard SPI config of MOSI=23, MISO=19, and SCK=18, but I did not see any default config listed for that.

No unique default, you may check some pins_arduino.h in each variants folder:

All have its own definitions.
