NUCLEO-WB55RG: As per UM2435, in document mentioned only 1 I2C and SPI. But in STM32CubeMX if check for the same board then it has 2 I2C and SPI

As per the UM2435 NUCLEO-WB55RG board has only one I2C- I2C1 and SPI-SPI1

But in STM32CubeMX configuration for the same board it has two I2C: I2C1 and I2C3

2 SPI: SPI1 and SPI2.

Can you please provide more information on this?

Thanks!

The chip itself has multiple I2C and SPI peripherals, but the pins used by these peripherals may not be exposed at a header on the board.

If you are looking for chip-specific information, consult the reference manual and datasheet. The user manual will contain board-specific information.

The default configuration for this board doesn't have any active I2C or SPI peripherals.
