I wonder, STM32F4 series can use USB VBUS 5V or not.
In fact, I have been using this device for 4 months with VBUS 5V directly, but it seems no specification of VBUS on DM00037051.pdfFor instance, I'm using like this case USB connector to CPU PA9 port directly.http://www.micromouseonline.com/2013/05/05/using-usart1-on-the-stm32f4discovery/
Nothing any problem long time for me, so It seems OK.If you know any opinion about this case, please show me the datasheet.Thank you.
