Confusion over NUCLEO-WB55RG vs P-NUCLEO-WB55
When navigating in the Board Selector from CubeMX, I see the following four related products:

- NUCLEO-WB55RG
- P-NUCLEO-WB55
- P-NUCLEO-WB55-NUCLEO
- P-NUCLEO-WB55-USBDONGLE
However, I only find two actual boards that correspond to them. So I attempted to make a mapping:

It's quite clear that P-NUCLEO-WB55-USBDONGLE corresponds to that small USB board. However, do the other three products (NUCLEO-WB55RG, P-NUCLEO-WB55 and P-NUCLEO-WB55-NUCLEO)all correspond to the same nucleo board? What's the difference between them?
I also figured that there are two different .ioc files in the database (see C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeMX\db\plugins\boardmanager\boards) related to this nucleo board (if you ignore the difference between "Board" and "Board_AllConfig"):

So, what is the difference between:
- J02_Nucleo_NUCLEO-WB55RG_STM32WB55R_Board.ioc
- J00_Nucleo_P-NUCLEO-WB55-NUCLEO_STM32WB55R_Board.ioc
Thanks a lot for your help to clarify this.
