Questions
How big is the 16seg Controller PCB?
It measures 64 × 72 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 16seg Controller use?
59 parts, built around the 74HCT541D, CH330N, W5500 and BC807. 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 16seg Controller KiCad files?
From the CatoLynx/16_Segment_Display_HW_Controller repository on GitHub, at the commit this page was made from: the board is 16seg_Controller.kicad_pcb and its schematic 16seg_Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 16seg Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask CatoLynx before reusing the design.
