PA13 on STM32L432KC

Is there a board schematic for STM32L432KC somewhere?
I want to acces pin PA13. But I can find no connector or easy acces point.

Thanks

No, because STM32L432KC is just a chip - not a board.

If you're referring to an ST board, go to its Product Page and look on the 'CAD Resources' tab; eg,

https://www.st.com/en/evaluation-tools/nucleo-l432kc.html#cad-resources

 

If it's a 3rd-party board, you will have to contact the manufacturer and/or supplier

Note that PA13 is the SWDIO pin - so using it for anything else will interfere with your ability to program & debug the chip ...

Also PA14 is SWCLK:

Hello,

The board schematic is here.

As said by @Andrew Neil  PA13 corresponds to the SWDIO pin. So need to take care about that point.

Yes, that's the schematic for the NUCLEO-L432KC board - but @TVan .8 didn't say what board they have ...

Thanks, found them. I was looking under 'documentation'

So you are using the NUCLEO-L432KC board, then?

If your question is now resolved, please mark the solution on the post which answered it (not this one!)

@mƎALLEm that's a common "mistake", but it seems an entirely reasonable place to look !

Could this be better signposted, please?
