Questions
How big is the LightBoard PCB?
It measures 47 × 43.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LightBoard use?
28 parts, built around the ATTINY85-20PU. 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 LightBoard KiCad files?
From the stuenkels/LendingLibrary-LightingController repository on GitHub, at the commit this page was made from: the board is KiCad/lightBoard.kicad_pcb and its schematic KiCad/lightBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LightBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask stuenkels before reusing the design.
