# gps = adafruit_gps.GPS(uart, debug=False) # Use UART/pyserial

When using the example with an Ultimate GPS Featherwing it complains busio is missing while using UART. Recommend adding import busio commented out in the import section or use an import try/except for it.

try:
    import busio
except ImportError:
    raise
uart = busio.UART(board.TX, board.RX, baudrate=9600, timeout=10)
gps = adafruit_gps.GPS(uart, debug=False)  # Use UART/pyserial
# gps = adafruit_gps.GPS_GtopI2C(i2c, debug=False)  # Use I2C interface```
