Questions
How big is the Lcduino PCB?
It measures 86 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lcduino use?
31 parts, built around the AO3401A, BAV99, SMBJ18A and SS13. 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 Lcduino KiCad files?
From the bpmine/modules_uino repository on GitHub, at the commit this page was made from: the board is lcduino/hard/lcduino.kicad_pcb and its schematic lcduino/hard/lcduino.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lcduino design in my own project?
Its repository states no licence, so its author keeps all rights: ask bpmine before reusing the design.
