Boatcontrol is an open hardware design for a marine grade SMART/IoT electrical distribution panel and electronics platform (boat) controller.
It’s an I/O breakout board capable of switching 32 onboard latching relays and optionally 32 momentary/latching relays using addon boards switching up to 60A AC/DC 0-400V per circuit.
The "smart" part is provided by either a Raspberry Pi HAT or a Nvidia Jetson (Nano/Xavier NX) either of which can be mounted on the board.
