Baseboard DC-006 centre tap? - Bazmundi - 07-13-2020
For the SOPINE base board, the information in schematics does not make clear whether the 3.5mm power is +ve or -ve centre tap. That would be J2. Before people jump at this, a non-typical symbol is being used in the schematic.
Yes I understand the +ve "lines up" visually with the centre tap, but who really wants to pump 3 amps the wrong way around into a board that takes months to turn up in the mail just to buzz out the connections
Any hints please?
Might that detail be added to https://www.pine64.org/baseboard/ perhaps as I suspect I am not the only person that would have that question.

I was also confused by this (I ordered the SOPINE base board without a power supply). I took the risk - the Pinebook Pro power supply,which seems to be the same as the one for the Rock64/Pinebook/ Pine H64, has a fitting barrel connector and works fine with the base board.
From the Pinebook Pro schematics, it seems that the center tap is +ve, but it's probably safest to use a voltmeter to confirm this...
