I would like to know which is the 2.1mm DC jack used in Volumio Primo PSU.
I have to power it with a 5V power supply, but I don’t understand which is the correct jack to be used.
I tried a 2.1mm jack but it seems this is different in its inside from the jack used in Volumio Primo PSU.
Hi achim1812, thank you very much for your answer.
OK for the polarity.
I have a linear PSU and a 2mt male-male 2.1mm connector cable, very similar to that on your photo, but this is not OK for plugging it inside Primo.
Primo PSU connector seems to have a “cut” inside it.
The strange thing is:
I can plug Primo PSU connector inside my linear PSU female side
I can plug (both sides) my male-male cable inside my linear PSU female side
I can’t connect (both sides) my male-male cable inside Primo
I now bought the following:
I wish this is correct (you can see in it a “cut” like on the Primo PSU connector)
