Questions
How big is the CEM60 USB CommBoard PCB?
It measures 48 × 38 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CEM60 USB CommBoard use?
23 parts, built around the MAX3232ID. 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 CEM60 USB CommBoard KiCad files?
From the xlazam01/CEM60_USB_CommBoard repository on GitHub, at the commit this page was made from: the board is CEM60_USB_CommBoard.kicad_pcb and its schematic CEM60_USB_CommBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CEM60 USB CommBoard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
