  • Any flash memory that is compatible with the SFDP standard as defined in JESD216B

Footnotes

[*]ESP32 support will remain in beta till the ESP32 core can be installed via the Arduino boards manager.
[†]ESP32 boards usually have an SPI Flash already attached to their SS pin, so the user has to declare the ChipSelect pin being used when the constructor is declared - for example: SPIFlash flash(33);
