Questions
How big is the PWM amp PCB?
It measures 84 × 84 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PWM amp use?
53 parts, built around the NC7SVU04P5X, FDD8447L, XT30UPB-M and SMCJ18A. 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 PWM amp KiCad files?
From the YingK8/FlyingRobotsLinLiweiLab repository on GitHub, at the commit this page was made from: the board is PCB/PWM_amp/PWM_amp.kicad_pcb and its schematic PCB/Capacitors/Multi_capacitor/Multi_capacitor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PWM amp design in my own project?
Its repository states no licence, so its author keeps all rights: ask YingK8 before reusing the design.
