  • Datasheet says that it's 1Hz NMEA-0183 Ver 3.01 via a 9.6K baud serial. NEMA 0183 is an ASCII plaintext protocol that you can find the specifics of by googling around. Here's a wikipeida article on the protocol: https://en.wikipedia.org/wiki/NMEA_0183 , and the data sheet goes into the protocol some as well. The datasheet also specifies that TX is UART Serial Data Output, so I'm led to believe that it's wired properly.

    The datasheet also does specify that: "NMEA Output Messages: the module board outputs the following messages..." listing GGA, GLL, GSA, GSV, RMC and VTG. So without input, it should be sending at least those messages.

No public wish lists :(
