Questions
How big is the AmplifierBoard PCB?
It measures 210 × 104 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AmplifierBoard use?
243 parts, built around the ATMEGA328PB-AU, LM2576S-12, LM358 and 74HC14. 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 AmplifierBoard KiCad files?
From the dangrie158/AmpStation repository on GitHub, at the commit this page was made from: the board is AmplifierBoard/AmplifierBoard.kicad_pcb and its schematic AmplifierBoard/AmplifierBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AmplifierBoard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
