NavHat or Navigaion Hat is a Raspberry Pi HAT made for saling boats. The HAT implements a number of features to make the Raspberry Pi suitable for a sailing boat environment. It provides power to the Raspberry Pi from board supply, collects data from NMEA bus and attached sensors. It provides the hardware base for an Open Source Navigation platform.
Features:
- Powered by board supply of 12-28V DC
- Onboard fuses for Raspberry and power outputs
- Four Power Outputs of up to 6A with current and temperature monitoring
- Very low sleep current
- Wake-up by key or RTC
- barometric sensor
- CAN interface for NMEA2000 network
- RS232 and RS422 interfaces for NMEA0183 devices
- Sensor interfaces with STEMMA and Qwiic compatibility
- Designed for compatibility to Raspberry Pi HAT specification
The board is designed using KiCad. For more details, see the corresponding documentation.
I hope you like the project as much as I do. In case of interest of the board itself, please contact me.

Questions
How big is the NavHat PCB?
It measures 65 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the NavHat use?
177 parts, built around the MAX14830ETM+T, ADS1119IPW, BMP390 and LM62460QRPHRQ1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the NavHat KiCad files?
From the Ch-Schilling/NavHat repository on GitHub, at the commit this page was made from: the board is KiCad/NavHAT.kicad_pcb and its schematic KiCad/NMEA Interface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NavHat design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ch-Schilling before reusing the design.
