So the V- gets connected to the ground? Wouldn't that short the negative voltage to ground and possibly cause a negative ground plane variance which could make the voltage going to the Pines be +5 -5 ie 10v?
Is that OK?
My son fried my $250 Digital/Analog Trainer that way (+5 to -12, the Trainer was rated for 15v) and it was a pain to fix...well...not that hard other than sourcing components, desoldering, resoldering and testing 5 PSU circuits (+12, -12, +5, -5, variable +; the low noise ground somehow survived...).
