Using aviation connectors instead of db-style connectors Answered
I'm working on an arduino build that calls for a db9 connector, but cutting a nice, clean hole in a small, plastic project box for a db9 connector is difficult and messy. I would like to substitute a round connector so I can just drill a hole, and I came across "Aviation connectors." Would these be a decent replacement for db connectors? If so, why aren't they used more often? Is there some disadvantage when carrying a small (3.3v or 5v) DC signal? They are often rated for something like AC 200V 5A, which is total overkill, but would it be a problem?
Here's what I'm looking at on Amazon: Hilitchi 32-Pieces 6 7 8 9 10 Pin 16mm Thread Male Female Panel Metal Aviation Wire Connector Plug Assortment Kit
If this will work as well as the db9, I wouldn't mind buying the whole kit and having some round-hole options for other projects.
Google searches have not been very helpful, and tend to give a lot of results for one or the other type of connector.
Thanks in advance for any guidance!
