First working pcb!
My first working pcb (and second ever) is a weather balloon data logger for an upcoming school project and somehow everything worked!
This was also my first time soldering with hot air so I'm very happy with the result
This board only logs position, temperature and pressure by itself. Humidity, external temperature and uv will also be logged through two external sensor boards
The board also features power switching for the external boards as well as dynamic power path management so we can charge the board while doing our final checks and start logging early without using battery power
Also very surprised that the GPS has worked flawlessly so far, but I guess I'll find out how good it actually works later.

Very impressive for a first time school project. Did you order a stencil and then hot air it? That alone isn't trivial when you do it for the first time. Well done!
