Questions
How big is the Slowdds PCB?
It measures 28 × 25.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Slowdds use?
34 parts, built around the STM32F030F4P6, FAN2558S33X and AD9833BRM. 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 Slowdds KiCad files?
From the brightcloudy/pcb repository on GitHub, at the commit this page was made from: the board is vna-steps/slowdds/slowdds.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Slowdds 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).
