Questions
How big is the Decoder PCB?
It measures 90.8 × 53.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Decoder use?
25 parts, built around the 74LS540PC. 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 Decoder KiCad files?
From the jjyothilinga/PCB_Decoder repository on GitHub, at the commit this page was made from: the board is Decoder/Decoder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Decoder design in my own project?
Its repository states no licence, so its author keeps all rights: ask jjyothilinga before reusing the design.
