Questions
How big is the LocalFab PCB?
It measures 99.8 × 98.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LocalFab use?
170 parts, built around the TP181A1-CR, XL1509-5.0E1, AMS1117-3.3 and HGN036N08S. 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 LocalFab KiCad files?
From the CUERT-dev/SUPERMOD_PE_DEV repository on GitHub, at the commit this page was made from: the board is localFab/localFab.kicad_pcb and its schematic 13S_PSU_V0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LocalFab design in my own project?
Its repository states no licence, so its author keeps all rights: ask CUERT-dev before reusing the design.
