In the world of marine electronics, data is as critical as fuel. For decades, the standard for transmitting that data—from a GPS to a chartplotter, or from a wind instrument to an autopilot—has been NMEA 0183 . While its successor, NMEA 2000, has gained popularity, NMEA 0183 remains ubiquitous, particularly for outputting data from sensors to legacy devices, single-board computers (like Raspberry Pi), and VHF radios. nmea 0183 output

For the foreseeable future, every new GPS sensor and VHF radio will include at least one NMEA 0183 output port. Understanding how to configure and wire it ensures your electronics will never be "dead in the water." When buying a new device, always check the technical specifications for "NMEA 0183 Output Sentences." A cheap GPS may only output GGA and RMC, but a sailing instrument may output MWV, MTW, and VHW. Ensure your Talker speaks the sentence your Listener needs to hear. $GPGGA,123519,4807

The key constraint is this: All other devices on that circuit must be "Listeners." The Anatomy of an NMEA 0183 Output Sentence When a device produces NMEA 0183 output, it sends strings of ASCII text. These are called "sentences." A typical sentence looks like this: For the foreseeable future, every new GPS sensor
