Cool, thanks.
I like to use DIO3/ValidHeader to (subtract a constant value to) get an accurate timestamp
of when a packet is received. I would need a flywire.

Looks like PPS is connected as TIME_PULSE. LilyGO has gotten better about hooking up the
DIO pins lately and this one even has DI0-2

Is there any schematic for the pcb? It would be helpful to know if/how they connected
the GPS’s PPS signal, the SPI’s CS and the LoRa’s DIOx pins to the microcontroller.

Hi all
I spotted these boards yesterday: https://www.aliexpress.com/item/4000469332610.html
<https://www.aliexpress.com/item/4000469332610.html> They have onboard GPS.
It looks like Grant will try to support them:

So if you are thinking of buying some test hardware and have some technical skill they
might be a good choice.
I think it would add a lot to the usefulness of the devices.
I guess it would be good to have a coarse or precise setting. If I'm just driving
around day to day I may not want to be tracked, If I'm about to go and fight a
bushfire I'd probably be happy for people to know exactly where I am.
Are you planning to incorporate a GPS into the custom boards that are under development?
Thanks
Sam
