Questions
How big is the Fmcw nightly PCB?
It measures 94.6 × 83.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Fmcw nightly use?
446 parts, built around the SKY65404-31, L7980, TPS7A91DSK and 5400BL15B050E. 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 Fmcw nightly KiCad files?
From the matthuszagh/fmcw repository on GitHub, at the commit this page was made from: the board is hardware/boards/rev2b/fmcw_nightly.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fmcw nightly design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
