Questions
How big is the Amp board PCB?
It measures 64 × 115 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Amp board use?
198 parts, built around the OPA2196ID, NE5532DR-MS, PCM5102APW and RC0603FR-0710KL. 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 splogdes/Audio-Engine-A5-Input-Stage repository on GitHub, at the commit this page was made from: the board is amp_board.kicad_pcb and its schematic amp_board.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 splogdes before reusing the design.
