Questions
How big is the PCB piezo filter v3 PCB?
It measures 118.3 × 42.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB piezo filter v3 use?
48 parts, built around the TLC2262CP and TL062. 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 PCB piezo filter v3 KiCad files?
From the djorgeext/PCB_piezo-filter_v4 repository on GitHub, at the commit this page was made from: the board is PCB_piezo-filter_v3.kicad_pcb and its schematic PCB_piezo-filter_v3 (Copy).kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB piezo filter v3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask djorgeext before reusing the design.
