Questions
How big is the Amp board PCB?
It measures 223.5 × 147.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Amp board use?
760 parts, built around the 530002B02500G, 1N4148WX-TP, 150060VS75000 and BAT54JFILM. 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 Amp board KiCad files?
From the Alex-Wolfe/Home-Audio-System repository on GitHub, at the commit this page was made from: the board is Hardware/Design/Main Board/Native Kicad/amp board.kicad_pcb and its schematic Hardware/Design/Main Board/Native Kicad/20V Lin Reg.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Amp board design in my own project?
Its repository states no licence, so its author keeps all rights: ask Alex-Wolfe before reusing the design.
