Questions
How big is the Daughter PCB?
It measures 65 × 28.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Daughter use?
18 parts, built around the L80-R, B2B-XH-A and ICM-42670-P. 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 Daughter KiCad files?
From the nchunyady/Capstone repository on GitHub, at the commit this page was made from: the board is daughter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Daughter design in my own project?
Its repository states no licence, so its author keeps all rights: ask nchunyady before reusing the design.

v1 is broken and required some bodge wires to work. I have not updated the schematic and PCB to correct my mistakes. It also has some deficencies in the dimming circuit resulint in a quiet, but audible whine.
