RAK 4631 pin numbers

Is there somewhere I can get a list of the pin numbers used on the 4630?
For example, on the LPWAN-Tracker sketch in main.cpp there are 3 pins used with no comment explaining what they are doing. They are 17, 34 and 37.

It would be useful to know what all the pins are.

Thanks,
Alan

Can you give a link to this example please. Using numbers instead of WB_xxxx is quite unusual in our examples.

Hi @beegee
Here is the link.
I’ve resolved the first 2 , but not the third.

Thanks
Alan
