NMEA 0183 to WiFi Bridge
A beginner DIY build — just five wires, no coding. Connects your existing NMEA 0183 instruments to your boat's WiFi so you can see GPS, AIS, depth, wind, and speed on Navionics or any chart app. Built on a readily available ESP32 development board — parts cost a few pounds.
