My last commit
addresses the following:
Added bulk capacitance close to esp32
added more girth to 3v3, 5V and GND nets, added thermal reliefs where applicable
fixed text from previous revision being mirrored where it should not be
added a lot of text regarding the correct side for components/soldering
cleaned up routing in general, made it a bit more compact
added SAO 1.69ibis connector on the abdomen for future extendability
covered up exposed traces on the neck
lots of other various tiny tweaks
