RAK2247 GPS PPS Pin Signal

Reviewing the user manual, I see GPS PPS is on pin 19. There is no PPS pin reserved in the Mini-PCIe specification.

  • I wanted to find out more about how Pin 19 was chosen and if this is any kind of standard for RAK or LORA or other IoT specifications.
  • Could this pin change in the future or on other projects? Or will PPS always be on 19?

Information is appreciated.

Thank you,

I wanted to follow up on this thread to find out if any RAK employees had any information.
