Orange Pi Zero 3 2GB?

[AndyV]

does pypilot run on the orange pi and read from the sensor?    The minimal setup would be to ensure a hardware serial port on the orange pi is working, and wire that to a motor controller.    Once you have this it is sufficient.    Getting the lcd display and other stuff (like pypilot hat) you might run into a few issues, but there is technically nothing preventing it.    I had pypilot running on the orange pi 5 years ago and it did work, but I stopped using it because the orange pi zero used twice as much power as the raspberry pi, and it didnt support tinycore linux which I considered more stable (doesnt depend on microsd card once booted)

Have you got a rough idea of what the power consumption is with the Raspberry Pi (and which version). Have the Orange Pi running, installing dependencies and then will be looking at linking sensors and to SignalK. Once I get it set up (if I do), curious to compare numbers.
