• Usage see here

The board does not have a "detect SD card present" pin. Manually write 0 to pyb.Pin.board.SD_SW to force pyb.SDCard().present() True.

>>> import pyb
>>> import os
>>> pyb.SDCard().present()
False
>>> from machine import Pin
>>> sd_sw = Pin(pyb.Pin.board.SD_SW, Pin.OUT)
>>> sd_sw.value()
0
>>> pyb.SDCard().present()
True
>>> sd_sw.value(1)
>>> pyb.SDCard().present()
False
>>> sd_sw.value(0)
>>> pyb.SDCard().present()
True
>>> os.mount(pyb.SDCard(), '/sd')
>>> os.listdir('/sd')
['bmp.py']

Put the SD card’s filesystem in the path list so Python scripts can be imported from the SD card.

>>> import sys
>>> sys.path
['', '/flash', '/flash/lib']
>>> sys.path.append('/sd')
>>> sys.path.append('/sd/lib')
>>> sys.path
['', '/flash', '/flash/lib', '/sd', '/sd/lib']
