Questions

How big is the Veffy PCB?

It measures 39.9 × 80.8 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Veffy use?

192 parts, built around the ADF4112BCPZ, 74LVC1GU04DRL, AD9834BRU and AP2112K-1.8. 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 Veffy KiCad files?

From the scooterthedev/veffy repository on GitHub, at the commit this page was made from: the board is veffy.kicad_pcb and its schematic veffy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Veffy 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).
