2.2uF/100V are not really available in a 0805 package. This part of
the PoE design a 25V rating is sufficent.

Order some relevant reference designator. Use JP for all jumpers. Place
silkcreen neatly. Add some custom silk screen. Remove heat sink corner
marks on silk screen.

Use JLC7628 impedance values to get more options in color selection.
Also this leads to slightly wider traces typically, and it will be
easier to switch back to JLC2313 or the like than the other way around.
Also swap placing of HDMI/SW2 and rotate the heatsink by 90° for easier
routing.

Adjust some high level placement like M.2 or CM4 and heatsink. Remove
all traces and vias since most of the layouting has to be redone
anyways.

Instead of using VBUS to power CP2102N use the main/NVMe 3.3V supply.
This makes sure that the device stays powered during reset, while making
sure the CP2102N is always powered and doesn't backfeed if no USB is
plugged in.

- Replace unusual/high value ceramics with lower value in parallel
- Use the same protection Shottky Diode in PoE as in regular input
(B340LB-13-F)
- Replace PoE rectifier Diodes with B1100-13-F
- Replace PoE Inductor (SRN6045TA-3R3Y) with the same part from 5V power
supply (Taiyo Yuden NRS8030T3R3MJGJ)
- Correctly specify Pulse Electronics transformer

Remove power/reset/recovery switch. Power and reset is not really required
and recovery mode (USB Boot) can be triggered via jumper. Make the Fan
and RPiLED a new separate config so we can leave them unpopulated. Add a
second GPIO controlled switch.

Make sure those signals are well defined even when not be driven from
the CM4 side. Also rename Radio.BOOT to Radio.~BOOT since its a low

Use the correct footprint for the PoE bulk capacitor C80. The TI
evaluation module circuit uses a Panasonic EEE-FK1J470P bulk capacitor.
The series has other better suited alternatives like EEE-HA1J470UP, but
the F-size code seems to be a sensible choice.

Add the CM4 board to board connectors using separate symbols. This is a
bit a hack, but makes sure two pieces appear in the BOM.
Also, this seems to upgrade all the schematic to the latest KiCad
schematic version.

The 1- at the start of the part number denotes M-Key which is a rather
important distinction. Fix the footprint name.

We don't plan to populate those connectors by default. The through-hole
