Questions
How big is the LC79D PCB?
It measures 37.6 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LC79D use?
26 parts, built around the TXB0104D and AMS1117-1.8. 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 LC79D KiCad files?
From the Scouttman/LC79D repository on GitHub, at the commit this page was made from: the board is LC79D.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LC79D design in my own project?
Its repository states no licence, so its author keeps all rights: ask Scouttman before reusing the design.
