NUCLEO-L476RG as USB FS serial device

[MSuhe]

Is the CN1 USB Mini-B connector on the NUCLEO-L476RG board also connected to the STM32L476 target? Or it is only for ST-LINK-V2-1 section.

If the CN1 connector is only for ST-LINK-V2-1 then one has to solder a USB socket to the STM32L476 target to use it as USB FS device?

The schematic should be pretty clear on this, pull the manual and review if you haven't done so.

The mini-USB connects only to the F1 part providing ST-LINK functionality. You'll need to manually wire USB connectivity to the L4. Perhaps consider an Nucleo-144 board that has two USB, one connected to the target.

Thanks for your response. I am planning to hay-wire a USB mini-B connector to the relevant IO lines on the ST morpho connector. So that i can use the USB port on STM32L4 target.

Is there a schematic that i use here for reference. I am aware of the USB pinout and should be able to hay-wire the connector. But, just wanted to know if i need to have any diodes etc in the circuit for protection.

Thanks.
