Yes.
These are the voltage readings with nothing connected on several power
supplies options I have:
Voltage Readings
Pin Function USB Power 5V 0.8A HUB 5V
8A power supply
P1-5 Vbus 0 0
0
P1-7 VIN 4.97 5.152
5.163
P1-14 3.3V 3.422 3.422
3.422
P 1.24 Vout 4.925 5.108
5.118
I can not talk to the pb when its on the 5V 8A, but nothing shows up in
either on usb power or on a usb power hub.
I just connected it to see if it had any voltage impact.
Thank you.
