Power issue using USB

Post by tuf »

I've had my original CosmosEx since 2016 and it's worked fine all this time. However, the other day I noticed my network wasn't working, so I took the unit apart to check it out.

What I found is that when USB power is plugged in to the Cosmos board, the network adapter on the Pi drops the connection (all the lights go off) every few seconds. If I power the Pi directly it works as it should with the Cosmos board attached.

So I had to run power to the Pi, and it works fine again, but now I have no power switch :(

Has anyone seen this issue?

YES.. I was just posting I had the same issue.. it can be your cable or psu is not transmitting as well as it did before..

I just figured mine out.. I had a TINY pit of metal get on a couple of the pins.. If you have it apart.. spray it with ISOPROPO and blow it off with air.. clean it right up.. and try again.
