Mesh Tracker

I’M ON A TRAIN!!!! Toronto to NYC so lets get some work done

Internet Kinda Sucks.
CADed a housing
Added mounting Holes

Forked meshtastic and did some simple mods

Hours: 4

Feed the PCB into a LLM to catch mistakes, caught a bunch of missing pull resistors

Also gave it to friends, I missed all my decoupling caps 😭

Hours: 8

Grinded out the rest of the schematic and started initial layout

Side note:
Spent way too long getting everything placed correctly, Why does Kicad suck so much

for the display I had to do weird transform stuff and a flat section for the USB C had to be done in on shape and exported, and the I had to do weird transforms because I could not align to the center of the “arc”

Hours: 5

Started choosing the ICs that will be used. I chose the GPS chip and a maganometer.

GPS: MAX-M10S-00B
Widely available and was simple enough to implement

Mag: QMC5883P
Used it in a previous project

Rediscovered how USB C works With the CC pins. Did usb stuff and voltage regulation stuff to be able to run the WIO off usb.

Initial Microcontroller research and selection. I chose the Wio-S3 for it’s use of external antennas (Less RF to deal with)
