Sailor Hat with ESP32

[mairas]

Hi all,

Let me introduce Sailor Hat with ESP32 (SH-ESP32). The SH-ESP32 is an ESP32 development board designed specifically for marine use, featuring an integrated 8-32V protected power supply and an integrated NMEA 2000 compatible isolated CAN bus interface. It allows you to create custom sensors and control devices that connect to Signal K and OpenPlotter or directly to NMEA 2000. The board includes opto-coupled signal input and output (one channel each), as well as protected 1-wire and I2C interfaces. There's also a micro USB port for flashing and direct host communication as well as a GPIO header exposing all usable ESP32 GPIOs. Finally, the board includes an ample proto board area for customizations.

Example use cases:

• NMEA 2000 USB gateways
  
• Temperature monitoring
  
• Tachometers (RPM meter)
  
• Tank level monitoring
  
• Relay controlling (lights, blowers, anchor winch)
  
• Attitude sensors
  
• Electronic compasses
  

The design is open and available at GitHub. The board documentation is available at GitHub Pages. SH-ESP32 including bundles with enclosures and connectors is available for purchase at hatlabs.fi.
