Questions
How big is the Butler PCB?
It measures 160 × 100.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Butler use?
58 parts, built around the BAT54S and BZX84J-B5V1. 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 Butler KiCad files?
From the poultry-butler/hardware repository on GitHub, at the commit this page was made from: the board is butler/version-0.2-prototyping-pcb/butler.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Butler 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).
