Any recommendations on an affordable, submersible bulkhead connector with a USB port, or a penetrator that could accommodate a USB port, but be sealed off completely while underwater? I want to be able to make a USB connection to what’s inside my waterproof housing when out of the water, but have a cap on it to seal it off from water when underwater. (I.e. no attached cable when underwater…)
So far my searches online are only bringing up IP67 “waterproof” USB connectors that only seem to be made to keep rainwater out. Or extremely pricey connectors like these:
Any recommendations for anything more affordable?
