LoRA GPS beacon and texter (pair)
a low power gps and texter that requires 0 infrastructure, and can last multiple days (i hope)

I hate + love looking at datasheets
stared at the datasheet and integration manual for the ublox max m10s for a rly long time trying to figure out how to properly wire the antenna and stuff because for some reason NO ONE ON THE INTERNET EVER TALKS ABOUT PASSIVE ANTENNAS DSAJLKFGJDSKLFAJDS;LKFJDLKFJA
ahem anyways uh after the terrible amount of research I believe my current setup is ok
Apparently the module already has a dc block cap so it should be fine with a wire directly to the antenna
I might need to add some ESD prevention components tho idk
I need someone that actually knows what they're doing to help :Sob:

more research and headache
more researchhhhhhhhhhhhhhhhhhhhhh
decided on the ublox MAX M10s gnss module, since it's really low power
stared at the integration manual and looked everywhere for wiring info but I'm still kinda confused, but I think this layout should work (some feedback got was to add some capacitors which i'll do in a bit

doing some research and starting the schematic
doing research for this did take a while :sob:, but I was able to find some sources for the batteries I will need, as well as research on some gps modules, screens, how long the battery would last this device etc
hopefully I will be able to get 2 2200mah batteries (one for each transiever end) (which can sustain the device for pretty long, potentially a week without charge)
anyways here's the progress on the schematic for now
