Questions
How big is the Filter PCB?
It measures 68 × 46.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Filter use?
26 parts, built around the LM324. 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 Filter KiCad files?
From the icedomazet/Amp-Filter repository on GitHub, at the commit this page was made from: the board is Filter/Filter.kicad_pcb and its schematic Filter/Filter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Filter design in my own project?
Its repository states no licence, so its author keeps all rights: ask icedomazet before reusing the design.
