This module is based on the "34x9 LED Matrix" example from https://github.com/FrameworkComputer/InputModules and is powered by a Raspberry Pi RP2040 microcontroller.
A short video demo of first light from the prototype is at https://youtu.be/MXg15aWYOqI

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.
