Title: Which polarity on the power supply?
Post by: mawg on April 09, 2011, 03:24:03 am
The details are obscured on the back of my board. I want to use one of those universal power supplies, so I will set it to 5v, but what about inner/outer, which is + and which -  ?

Thanks

Hi mawg,

The center pin is +5, the outer barrel is ground.
