What is the digital pins's frequency of Nucleo-f303K8?

I tried to find the frequency that the digital ports of Nucleo-F303k8 can accept data (example: the arduino works with 10kHz on these pins), but i couldn't find anywhere. Someone can help me? I need to use some sensors and I need this information to but them.

Well, it's not super clear what you're asking as "can accept data" is pretty vague. If you're asking about maximum speed the GPIO pins can switch, it can be found in "Table 53. I/O AC characteristics". Maximum SPI/I2C speeds can be found in the very first sentence of their respective sections.

That info will be in the datasheet. They can generally drive or be driven by signals of tens of MHz without issue, but consult the datasheet if you need details.

this way you dont find finish...

try write how sensor how bus.

For example SPI can clearly work on 25MHz...
