This repository contains the Sailor Hat for ESP32 (SH-ESP32) hardware design. SH-ESP32 is a powerful microcontroller development board designed for marine environments.
Special emphasis has been placed on electrical compliance: the board can handle most power surges ever present on an automotive or marine 12V or 24V power system. Equally importantly, the inputs and outputs have protection for electrostatic discharges (static electricity), and are designed to not produce electromagnetic emissions (disturb other sensitive devices such as VHF radios or GPS antennas), and to be protected against electromagnetic interference (will not be disturbed by a VHF, SSB, or a radar).
SH-ESP32 can be used to easily create different types of sensors and control devices for boats. Use scenarios include:
Some of these applications require a small amount of additional components. Simple add-on boards and designs for these will be made available.
Since the board has native WiFi and NMEA 2000 compatible CAN bus connectivity, it can be used to create boards with either Signal K or native NMEA 2000 connectivity (or both!).
The main design features include:

SH-ESP32 is available for purchase at the Hat Labs web store.
SH-ESP32 documentation is available at the project GitHub Pages.
