Hello, I run a program that opearates several ROVs of various sizes in the Pacific. We’ve used GigaBlox switches to great effect - thus far, they have always been located inside a pressure rated housing, well secured away from the sea. I have an application where I’d be looking for 100 MBps connectivity, and am wondering if it might be possible to cast SwitchBlox Nano into a waterproof/pressure proof cable splice. We typically fabricate these splices using 3M ‘ScotchCast’ 2131B compound. We would of course wire up the SwitchBlox and test is before filling the mold, but wondering if the SwitchBlox might still work if it were encased in solid potting compound. I suspect this isn’t something that’s been tested or designed for, so more looking for some guidance of ‘this might work’ vs ‘absolutely won’t work because of factor X’. Thanks very much, Ben ---

The main issue is heat dissipation, but SwitchBlox Nano’s power dissipation is low, around 1 Watt, so isn’t likely to overheat. I believe other customers are already doing this and it works.
