Questions
How big is the Amplifier2 PCB?
It measures 252 × 118 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Amplifier2 use?
196 parts, built around the AD8021AR, AD8017ARZ, AD8033ARZ and BAV99WT1G. 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 Amplifier2 KiCad files?
From the msayad97/Amplifier repository on GitHub, at the commit this page was made from: the board is KiCad/Projects/Amplifier2/Amplifier2.kicad_pcb and its schematic KiCad/Projects/A3/A3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Amplifier2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask msayad97 before reusing the design.
