Questions
How big is the FSK-66-20-C PCB?
It measures 285 × 108.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FSK-66-20-C use?
193 parts, built around the ATMEGA32U4-AU, 1N4148W, NANOSMDC050F/13.2-2 and RB161MM-20TR. 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 FSK-66-20-C KiCad files?
From the toms74209200/Order66 repository on GitHub, at the commit this page was made from: the board is pcb/FSK-66-20-C.kicad_pcb and its schematic pcb/FSK-66-20-C.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FSK-66-20-C design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
