Questions
How big is the Moni PCB?
It measures 64.8 × 66.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Moni use?
18 parts, built around the USBLC6-2SC6. 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 Moni KiCad files?
From the code2344/moni repository on GitHub, at the commit this page was made from: the board is moni.kicad_pcb and its schematic moni.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Moni design in my own project?
Its repository states no licence, so its author keeps all rights: ask code2344 before reusing the design.
