25b662e6fb hardware: pcb: re-route USB after flipping the footprint
It looks kinda janky, but it's better than ripping everything up and
starting over.

e91896a8fb hardware: pcb: loosen up the ground plane / 5V some more
Move some vias around to get the 5V plane more breathing room.  Add a
small pour to give more copper and stabilize the net.

e48d836372 pcb: remove usb silk, add more 5V vias
Add more 5V vias near the 1.2V regulator, and replace a manual trace
with a copper pour.  This will increase the amount of copper going to
both the 3.3V and 1.2V regulators, which should improve stability.

While we're at it, remove an errant silk artifact on the USB connector.

46fdfdf134 hardware: pcb: update drill offset, add mfg notes
Add a note indicating the PCB thickness and color.

Also, move the drill origin to the lower-left corner, to aid in machine
assembly.

12afe3aed1 pcb: add more silk, fatten up ground traces
Add more silk, indicating website and other info.

While we're at it, move some traces around to give more copper area, and
drop some more vias to improve ground performance.

b26b71343d hardware: first fully-routed PCB
The PCB is terrible, and probably would have all sorts of issues.  Will
rip it up and try again tomorrow.

e32b48a72e hardware: pcb: initial commit
This is an initial commit.  Still unclear of how big it will be, but
this is a good "minimum size" estimate.
