6a392e57d2 pcb: rework pcb with correct footprints, add tvs diodes
Add TVS diodes, so we make sure they work.

Also, rework the PCB so that the clock actually functions now.

70c3c758da hardware: pcb: update footprints and 3d models for pin 1 marker
Update the footprints so that the pin 1 marker is actually visible by
using silk where possible.

b8f4eb8cb3 hardware: pcb: fill pcb
Re-do the fill, because the last commit was done with an unpoured fill.

37ff812b49 hardware: pcb: replace "text" with "value" for buttons
Previously, we used text to display the "5" and "6" designators for the
physical buttons.  Replace this with a value of "5" and "6", and remove
the extra text.

Additionally, display "SW??" under the switch, to make hand-assembly
easier.

Do the same thing for the "Reset" button.

12eed495f2 hardawre: pcb: remove 3D models for headers
These are nominally DNP, so remove the 3D models to make the render more
accurate.

62dab34633 hardware: pcb: repour and connect wire in kicad
The `VCCPLL` line was listed as "Not Connected" in KiCad.  Reconnect it,
even though it was already connected.

74963bd034 hardware: pcb: fix virtual and smd designation
Some components were getting added to the BOM that shouldn't have been,
and some were missing from the pick-and-place file.

Update the `Placement Type` to be accurate according to assembly.

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.

It was only 11.3mm before.  Make it 11.7mm, and center it.

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.

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