Using moitessier hat and GPIO

[Ranur]

Snip...
I plan to buy the HAT as soon as it is available, but I also would like to use the GPIO's for sensors and switches. Is there a common breakout board or how do you guys solve this?

I use an esp32 and send the data as signalk over wifi, works really well and means you font have to go near the fragile Pi gpio pins.

So compared to Jim's suggestion. The advantage of using an esp 32 is the wireless connectivity, whereas the advantage of the Arduino is that I already have 12V in place on different connection points. I was planning to rebuild my boat circuitry - looks like I need to factor in not only 220V AC and 12 DC but also 5 V DC... Any hocus pocus to get the data from the esp32? Be gentle and explain it to me like I am dense ok..
