.. py:class:: SDCard(slot=1, width=1, cd=None, wp=None, sck=None, miso=None, mosi=None, cs=None, freq=20000000)

   This class provides access to SD or MMC storage cards using either
   a dedicated SD/MMC interface hardware or through an SPI channel.
   The class implements the block protocol defined by :class:`vfs.AbstractBlockDev`.
   This allows the mounting of an SD card to be as simple as::

     vfs.mount(machine.SDCard(), "/sd")

   The constructor takes the following parameters:

    - *slot* selects which of the available interfaces to use. Leaving this
      unset will select the default interface.

    - *width* selects the bus width for the SD/MMC interface.

    - *cd* can be used to specify a card-detect pin.

    - *wp* can be used to specify a write-protect pin.

    - *sck* can be used to specify an SPI clock pin.

    - *miso* can be used to specify an SPI miso pin.

    - *mosi* can be used to specify an SPI mosi pin.

    - *cs* can be used to specify an SPI chip select pin.

    - *freq* selects the SD/MMC interface frequency in Hz (only supported on the ESP32).
