This component enables and configures PSRAM if/when available on ESP32 modules/boards. It is automatically loaded and enabled by components that require it.

PSRAM is only available on the ESP32.

# Example configuration entry
  mode: octal
  speed: 80MHz

Configuration variables:

  • mode (Optional): Defines the operating mode the PSRAM should utilize. One of quad or octal.

  • speed (Optional, int): The speed at which the PSRAM should operate. One of 40MHz, 80MHz or 120MHz. Note that 80MHz and 120MHz are not supported on all modules; in addition, 120MHz is considered “experimental” at the time this document was written.
