Questions
What parts does the ClassD use?
27 parts, built around the TAS5825MRHBR and AMS1117-3.3. 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 ClassD KiCad files?
From the aokblast/ThunderChargeXPro repository on GitHub, at the commit this page was made from: the board is RC_Charger/ClassD.kicad_pcb and its schematic RC_Charger/ClassD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ClassD design in my own project?
Its repository states no licence, so its author keeps all rights: ask aokblast before reusing the design.
