I want to run both my Pi3 and Hifiberry Digi+ off a linear supply to see if it makes any difference in sound. My intention is to try powering both the Pi3 and Digi+ off a single power supply and then try powering the Pi3 and Digi+ separately. I just want to doublecheck with this forum before fry something.
Powering both Pi3 and Digi+ from same linear power supply:
All I need to do is supply 5V to P3 on the Digi+ board from power supply #1? This would supply power to both the Pi3 and Digi+. As I understand it, the Digi+ also needs 3.3V so it will still be able to get this from the Pi3 converting the 5V I am feeding it through the Digi+?
Powering Pi3 and Digi+ from separate power supplies:
I understand that the Digi+ needs both 5V and 3.3V. I need to still supply 5V to P3 on the Digi+ board. Do I then supply 3.3V to pin 1 of the GPIO on the Digi+?
I then need to cut pins 1, 2, 4 from the GPIO header on the Pi3 so that I am not providing power to the Digi+ board from 2 different power supplies. To power the Pi3, I just need to plug my power supply #2 into the micro usb port.
Thank you in advance for the help.
