[sdiy] Powering 4ms pod

[Didier Leplae]

Sorry, I was out of commission with a stomach flu for a couple days there.
I have a very cheap multimeter that I got at a convenience store, so testing continuity is a bit confusing. I am thinking the problem might lie with that RECOM 5v regulator. 
Testing resistance between any two pins gives a reading of somewhere around 1 to 2 ohms!

Seeing as none of my modules use the 5v rail anyway, it won’t hurt to just remove it for now. I just need to get my hands on a soldering iron.
