Full guide: https://spacemariner.space/guides/

1. Install CircuitPython 9.x for "Feather RP2040 Adalogger" (circuitpython.org/board/adafruit_feather_rp2040_adalogger/).
2. Download the CircuitPython 9.x library bundle (circuitpython.org/libraries) and copy these into CIRCUITPY/lib:
   - adafruit_ms8607.mpy
   - adafruit_gps.mpy
   - adafruit_ds18x20.mpy
   - adafruit_onewire/
   - adafruit_bus_device/
3. Copy code.py from this folder onto CIRCUITPY (replace the one there).
4. Insert a FAT32-formatted microSD card. The board restarts and logs once per second.
