Questions
How big is the Fmcw2 PCB?
It measures 40.3 × 22.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Fmcw2 use?
136 parts, built around the HMC313, HMC431LP4E, SKY65404-31 and LT6232IGN. 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 Fmcw2 KiCad files?
From the Ttl/fmcw2 repository on GitHub, at the commit this page was made from: the board is hardware/fmcw2/fmcw2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fmcw2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ttl before reusing the design.
