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.
