Yes. That will give you a 3.5v difference.
Comment on What is negative voltage?
CetaceanNeeded@lemmy.world 2 months agoJust so I understand.
In your example, let’s say we have a power supply that distributes 5v and 8.5v.
The extension board is easy, we just hook it up from 5v to 0v.
For the 3.3v chip, are we wiring it between 8.5v and 5v? So it only sees a 3.3v voltage difference?

Correct.
A good ‘at home’ example is your computer power supply
