so basicly what I have been doing for now is that I already sent out the project for funding review, but I thought while I wait I might make some small upgrades to the PCB. first I swapped out the through-hole pads for actual connectors (JST-SH?) which will make it much easier to connect the sensor boards. then I spent the rest of the time working on the PCB tracing I think I optimized it a lot more. next I have to double check all the PCB components and routing and then I have to prepare myself for my next steps when I get funding
