Hey,
Great use of USB PD on this project, I have a question about powering the Rockpi from voltage rails directly.
1st question:
Can I provide 5V via the GPIO?
2nd Question:
If I send a dumb 12v power into the USB C connector will that work?
Kind regards,
James
Hi, James
To answer your questions
Yes, you can power from the 5V GPIO.
Yes, a dummy 12V power is also supported(up to 20V). Remember no high voltage for the signal pin of usb type C, it may damage the power protocol IC(PD&QC trigger chip).
That’s great thank you!
