Hello STM members,


Currently i am working on STM32f429 (144-LQFN) controller.


For this project we have requiremnt USB_OTG_FS interface.


I have query regarding USB OTG connections.

1. Our system is working on 3.3v Now we want to connect USB micro-B connector to our controller.
2. If we connect USB device to our controller is there any problem because USB working on 5V.
3. Is there any level sifter is needed ?
