Development board with support for HS usb transfer

[CKusc.1]

Hello

I'd like to get a STM32 board that has support for HS usb transfer, but i'm not sure how to understand if a board supports it or not, how can i know? Is it enough for the STM32 chip to support it and to have a usb port on the board?

thanks

If you have a non-locked STLINKV3, it is a nice development board. F723 is the only STM32 with built-in HS phy, other chips need an external phy for HS

Hi i see, and if i wanted to add a phy that's something that can be done to a existing board or requires a custom pcb? do you know any custom pcb design that uses the f723?

The F723 Disco board exposes both HS and FS USB.
