Hi Everyone,
I'm working on a design and I'm not sure it will work properly.
Mainly because the USB is OTG and there is no VBUS connection between the boards.
I want to make a connection between two boards, each board has it's own power supply, there is no VBUS connection between the boards. One board will function as a master and the other as a device.
Does anyone have suggestions for repair/addition or advice on how to do it better?
I added a picture to illustrate the connection between the boards.
Hi Igor,
Thanks for the help.
Yes, I was thinking about this configuration, but when one is set as a device he does not expect to get 5V in VBUS? Will there be a VBUS on the side of the device or will I have to connect the VBUS directly to 5V?
>Will there be a VBUS on the side of the device or will I have to connect the VBUS directly to 5V?
on device side VBUS can be connected directly to 5V.
Best regards

Hi Daniel
for communication between two boards one can try to use usb unit tests, configure
one board as host other as device:
