I have an old GPS module from about 2002, the Laipac TF10 12 Channel SiRF module Though I would hook it up via a Arduino
Pulling in the serial0, serial1 of the module and 1PPS then extracting and outputting to another serial with a different BAUD on the arduino while extracting parts of the GPS stream data to be displayed on an LCD.
