Dual node Meshtastic and MeshCore. I think both networks have their benefits, and now I don't have to choose. We'll see how two nodes does in the winter. But right now a single solar panel is plenty to keep the battery constantly topped up.
In terms of layout, there were a few decisions. For antennas, it's because I didn't want to put too tight of a bend in either cable, preventing a crimp. Not sure if it matters. Likewise, the rak boards are pushed up as far as I can to keep enough room to easily access the USB ports should I need serial access.
