Might be better to put smaller boards into potting epoxy, cover pigtails connections with heat shrink tubing.
Larger boards into waterproof enclosures with cable glands for wires coming out?
There possible condensate water in such cockpit enclosures.
Thanks
This arrangement has been operating in the boat cockpit during eight months and is completely water tight. No water condensation is seen when inspected the inside of the box
Of course, there is no water vapor barrier, thus; can be potentially affected by the excess of humidity at long term. (But no very different of conditions for the RPI running OP in the boat's cabin during winter)
As the relay board will be eliminated, and the supply adapter is totally enclosed, I will study a small resin box tho accommodate the RPI inside with connections through tight seals. (good projects never are really finished!)
The display looks to be good enough for outdoor work (Sihovision sell those displays for marine equipment) and bezel material seems good enough for salted water sprays. (But, must wait two or three years to be sure...)
Thanks for your suggestion
