Questions
How big is the Dds3 PCB?
It measures 73.3 × 46.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Dds3 use?
66 parts, built around the AD9744ACPZRL7, LT86102UX and X50328MSB2GI. 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 Dds3 KiCad files?
From the jjmason/toy-function-gen repository on GitHub, at the commit this page was made from: the board is dds3.kicad_pcb and its schematic dac.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dds3 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).
