wow I realized, that im really bad at regularly writing a devlog. So what happened in the five hours since last time. I am nearly finished with the the PCB. But from the beginning… I am using a 4 layer pcb with signal layer, ground layer, 3.3v layer and another signal layer. Aside from this, I think that antennas and these differential pairs for ethernet and usb signal is black magic. It took a lot of time figuring out how to pick all the values and route it correct. I placed nearly all components and just need to fix my power management and fix all of the drc problems. I also decided to remove the extra i2c connector and lipo charging option, because they were a bit of a headache and I decided that it wasn’t worth the hassle
