We manually use the "File -> Plot" function because KiBot only
exports the first page (despite `all_pages: true`).

The other one is out-of-stock.

The JLC BOM tool sometimes doesn't choose the right part, e.g. extended
instead of basic or even the wrong one.

This seems to be the preferred/only way. *shrug*

The transceiver has plenty of ESD protection but a dedicated TVS
should be better.

This would be an additional type of component for the display
board but we already use that MOSFET on the main board. Furthermore,
the display board will be standard PCBA so we would also have to
pay a fee for the resistor.

Including a "cheap" knock-off of ringclock (and even the idea to
put it on this board was stolen from fxk8y *g*).

Otherwise, JLC will complain because one of the DNP parts is in the
same place as another part.

There were some unnecessary gaps due to previous changes.
