Questions
How big is the Class D Amp PCB?
It measures 90 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Class D Amp use?
87 parts, built around the UCC27201D, IPD180N10N3 G, TS4148 RYG and BZX84C5V6. 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 Class D Amp KiCad files?
From the iakop/E5SPK_ClassD repository on GitHub, at the commit this page was made from: the board is project_files/Class_D_Amp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Class D Amp design in my own project?
Its repository states no licence, so its author keeps all rights: ask iakop before reusing the design.
