Build System
I use tup as my primary build system. I usually will wrap tup in make commands. You can find tup here. I simply find tup to more reliable detect changed sources with less work.
Qt6_DIR Environment Variable
The Qt6_DIR Environment Variable needs to point to the installation location of Qt6, for example ~/Qt/6.6.0/gcc_64/. Your installation location may be different, so copy-and-paste is not advised.
EEPROM Programmer
I do not have a commercial EEPROM programmer. I use the TommyPROM programmer. You can find all the relevant information on TommyPROM here. In Linux, I use minicom as the interface. Hint: use sudo minicom -s to set up the defaults.

Questions
How big is the Led array-4 PCB?
It measures 11.7 × 14.2 mm and has 2 copper layers, 1.69 mm thick.
What parts does the Led array-4 use?
10 parts. 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 Led array-4 KiCad files?
From the eryjus/16bcfs repository on GitHub, at the commit this page was made from: the board is kicad/projects/utility/led-array-4/led-array-4.kicad_pcb and its schematic kicad/projects/16bcfs/clock-module/adjustable.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Led array-4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask eryjus before reusing the design.
