Datasheet

And further below:

Should all be uncommented and look as above. This will configure the code to write GPS NMEA data to the /sd/gps.txt

file, appending new data to the end of the file.

Once the example is running as a main.py on your board open the serial REPL and you should see the raw NMEA

sentences printed out:

Check the gps.txt file (either under the root or /sd path depending on how you setup the example) in a text editor and

you'll see the same raw NMEA sentences:

# Path to the file to log GPS data. By default this will be appended to

# which means new lines are added at the end and all old data is kept.

# Change this path to point at internal storage (like '/gps.txt') or SD

# card mounted storage ('/sd/gps.txt') as desired.

#LOG_FILE = '/gps.txt' # Example for writing to internal path /gps.txt

LOG_FILE = '/sd/gps.txt' # Example for writing to SD card path /sd/gps.txt

# If writing to SD card customize and uncomment these lines to import the

# necessary library and initialize the SD card:

SD_CS_PIN = board.SD_CS # CS for SD card (SD_CS is for Feather Adalogger)

import adafruit_sdcard

spi = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO)

sd_cs = digitalio.DigitalInOut(SD_CS_PIN)

sdcard = adafruit_sdcard.SDCard(spi, sd_cs)

vfs = storage.VfsFat(sdcard)

storage.mount(vfs, '/sd') # Mount SD card under '/sd' path in filesystem.
