Questions
How big is the Clap Switch Controller PCB?
It measures 41.3 × 44.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Clap Switch Controller use?
19 parts, built around the 74LS109PC, AOM-6545P-R, PR12-5V-360-1C and TIP122. 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 Clap Switch Controller KiCad files?
From the Haylie-dt/PCB-Projects repository on GitHub, at the commit this page was made from: the board is Clap Switch Controller/Clap Switch Controller.kicad_pcb and its schematic BMS SMD/1S BMS SMD Mode.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clap Switch Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask Haylie-dt before reusing the design.
