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.


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.


Hi Alan,
I don’t see a link
