I stacked up the two schematics to compare them, and the only differences are:
- IPS->SYS_5V step-up.
Old:
New:
- SYS_5V to USB_VBUS
Old:
New:
So… They reworked everything 5V! That’s why it’s called “V5”?
Also, the ID assignments have changed. R508 is no longer connected to EN. If anyone wants to have the USB_VBUS mod on V5, do it on R512 instead.
