Questions
How big is the Encoder debouncer PCB?
It measures 67.9 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Encoder debouncer use?
38 parts, built around the LM358 and LM311. 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 Encoder debouncer KiCad files?
From the enph253-2025-team5/encoder-debouncing-pcb repository on GitHub, at the commit this page was made from: the board is encoder-debouncer/encoder-debouncer.kicad_pcb and its schematic encoder-debouncer/comparator-schmitt.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Encoder debouncer 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).
