Questions
How big is the Timerbox PCB?
It measures 97 × 49 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Timerbox use?
29 parts, built around the ATTINY4313-PU, 78L05 and LM7812. 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 Timerbox KiCad files?
From the dunz0r/Circuits repository on GitHub, at the commit this page was made from: the board is Timerbox/Timerbox.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Timerbox design in my own project?
Its repository states no licence, so its author keeps all rights: ask dunz0r before reusing the design.
