Type C port for OTG in CM pi 4

AmitRS 1 month ago

Hello everyone,
I am designing my own CM pi 4 IO board. I want to replace the micro USB to type C. I have provided the schematic for the same. Please let me know if this is correct as I am working with type C for the first time. Thanking all in advance.

The connector end looks ok at first glance. The rest looks plausible, but I've not checked datasheets or any CM4 user guide. If you need this capability then you have to assemble it at some point anyway…

Could you try re-posting and checking your diagram - the writing is not legible.

If you need this capability then you have to assemble it at some point anyway, so you may as well just give it a shot and see what happens. The worst that will happen is that it might need a bit of tweaking/rework on your first PCB.

By the way, I'm sure you're aware, but the title doesn't represent what you've implemented.. there's no type C for OTG functionality there, you've configured for the remote end to be the USB host always when plugged into that USB C port.
