The Feather M0 Adalogger is a classic board that doesn't have the same power as its newer siblings, but it's still good for logging. Best of all, no soldering is necessary to access the SD card.
To mount the SD card, use the following code. Remember, to put it in the file mount_sd.py on CIRCUITPY so you can easily call it from code.py or the REPL with import mount_sd
.
import adafruit_sdcard import board import busio import digitalio import storage spi = board.SPI() cs = digitalio.DigitalInOut(board.SD_CS) sdcard = adafruit_sdcard.SDCard(spi, cs) vfs = storage.VfsFat(sdcard) storage.mount(vfs, "/sd")
