Fabrication and Assembly
A 0.8mm PCB is required.
Most components are SMT on the bottom side of the board; the seven segment displays and side-firing neopixel LEDs are on the top side. If you use a PCBA service, it is most economical to have the bottom side assembled and then hand-solder the small number of top-side components.
In addition, the threaded inserts are not generally stocked by JLCPCB and so are probably easier to hand assemble.
A bezel for the board, which can be 3d printed, can be found in
LEDMatrix-cover-Body.step. This was
designed in FreeCad and the source is LEDMatrix-cover.FCStd.
It is intended that 4mil transparency be used to create legends for the different sections of the display, and then the entire top surface be covered with 0.2mm ND film to achieve a consistent look. A template for the legends is in LEDMatrix-template.pdf and sample legends ready to print (or modify!) are in LEDMatrix-sample-legends.svg.

Questions
How big is the SevenSegmentInputModule PCB?
It measures 33.8 × 131 mm and has 2 copper layers, 0.8 mm thick.
What parts does the SevenSegmentInputModule use?
86 parts, built around the RP2040, 74LVC1G34GW,125-JSM, IS31FL3729-QFLS4-TR and W25Q16JVUXIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SevenSegmentInputModule KiCad files?
From the cscott/SevenSegmentInputModule repository on GitHub, at the commit this page was made from: the board is MainBoard/MainBoard.kicad_pcb and its schematic Bezel/Bezel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SevenSegmentInputModule design in my own project?
Its repository states no licence, so its author keeps all rights: ask cscott before reusing the design.
