The board also has a STM32F723IEK6 that runs STLink V3. A micro USB port is provided for the STLink. This version of STLink supports USB HS (480Mb/s) -- Much to my surprise, almost all F723 devices (including this one, the "IE") have an on-board USB HS Phy! So this can do 480 MG/s when plugged into a capable host port. And by golly, it does, I see this in the linux logs:
Apr 30 12:17:43 trona kernel: usb 4-1.6: new high-speed USB device number 66 using ehci-pci
It also sets up a second USB interface as a VCP (virtual console port), as well as some useless mass storage on yet another interface.
The board provides an RJ-45 for the ethernet and has an SMC 8742A for the Phy.
The board provides a Micro A/B for the HS/FS USB, and apparently a regular Micro USB
works with this.
Even though it would make no sense to use it for anything other than running the STLink firmware, it is worth noting some of the specifications of the F723.
