Questions
How big is the Clover timer PCB?
It measures 32 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Clover timer use?
6 parts, built around the PMS150G-S08. 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 Clover timer KiCad files?
From the akionu/clover-timer repository on GitHub, at the commit this page was made from: the board is pcb/clover_timer/clover_timer.kicad_pcb and its schematic pcb/clover_timer/clover_timer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clover timer design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
