I soldered some parts on the PCB, and worked on the CAD files some more

I did realize that I forgot some parts, so I ordered them on DigiKey. I’ll continue soldering the rest tomorrow. One of the parts was the LDO, which I only found out because I soldered the parts and realized that the voltage being put on the 3.3V rail is 5V

My project needs both versions of the same LDO and I only bought the 5V one
I also bought the wrong resistors. I’ve ordered them and they should arrive in a week or so.

My design of stacking the PCBs and then adding the buck modules in the middle might be very challenging, and I might need to stack multiple headers on top of each other to fit the modules inside. Hopefully it will still fit inside my arm segment and not short anything. There also needs to be sufficient airflow, which is def a challenge
